S5D-250G Interchangeability Question

So I have a 2003 325i. It is 07/2003 meaning that the S5D 250G-TAJT transmission comes from factory on it. I am in the works of a manual swap but now have remembered that the transmission I bought was from a 2005 325i which is the S5D 250G-TBDS.

Will the 05 transmission work with my 03 325i although they have different endings in the S5D 250G transmission (I do not know what that entails). Please let me know because I hope not to need to find another good manual trans assembly.

Diff and Transmission Fluid

I am going to change the manual transmission and differential fluid on my 2000 2.3 Z3. I have reviewed the forum discussion on the types of oils and folk’s opinions on the correct fluid to use and have a couple of questions. I apologize in advance for the long post. The specifics on the car are as follows:

2.5 ltr motor, with a Getrag S5D 250 G 5 speed transmission labeled MTF-LT 1. The car mileage is 102K and used primarily for year around pleasure driving in the mild San Francisco Bay Area climate. I may take some longer weekend get always with the car but it will not likely be in very hot or cold weather. As far as I know the transmission or differential fluids have never been changed.

I have narrowed the transmission fluid choices to: 1) Pentosin 75W-80 MTF2 Transmission Fluid as the equilvent OEM BMW fluid, or 2) Amsoil 5-30W Manual Synchromesh Transmission Fluid, not recommended application by the manufacture, but it appears a number of Z3 folks have used it and they claim provides better gear box feel and shifting. I would say my car shift quality is about 7 out of 10. Not terrible, but it could always be improved. However, being conservative I am leaning towards using the Pentosin.

My specific transmission fluid questions are: 1) Is it an issue that Amsoil at 5-30W is significantly different weight than the Pentosin at 75W-80. My reading indicates that the oil weight is not an issue when using synthetic oil presumably due to the better lubricating qualities. 2) Has anyone put a significant amount of mileage (over 20K) on their car using Amsoil and any longer term issues?

For the differential the Bentley manual states differentials from 1998 on (non M), BMW recommends synthetic lifetime gear oils (SAF-OX). From my reading it appears my car has an open/non-locking differential and not a limited slip differential. Currently I am not getting any noise from the differential and would like to keep it that way. The fluids I have found meeting SAF-OX include Castor Oil 75-90W and Red Line 75W-90 GL-5 Gear Oil. Any other suggestions that meet the SAF-OX standard.

QuestionE46 Getrag s5d 250 rebuild

Hello! This is my first post. I have been pulling my hair out to find information on rebuilding a Getrag 5spd found in a e46 325.

For a while now, my 3rd gear pops out on deceleration, I believe this to be a faulty detent spring/pin. I know there may be other factors, and I have bought all the parts necessary to eliminate this problem as long as it isn�t the synchro. However, I�m having difficulty finding the right repair parts/kit to make this job a breeze. I�ve seen plenty of videos on the Zf 320 5spd, and I know the two trans are similar, but not the same at all. My first question is, would a repair kit for a Zf 320�s detent pins/caps/springs also work for the getrag 250. I found a detent repair kit on fcpeuro.com but it says it only works for the Zf 320, but im seeing online in forums that the two trans share the same pins etc. I know I�m going to be told to just buy a Zf 320, but working with a budget, and cannot find one local. I just bought a valeo single mass flywheel clutch kit, throw out bearing, pilot bearing, input and output seal and a selector joint. I was able to find the correct pin and spring (detent) for my Getrag on fcpeuro.com, however I cannot find a cap. Also I�m not sure which hole on top of a Getrag 250 is the cap for 3rd gear. I know 5th and reverse are on the side.

you can probably tell I have a lot of questions about this.. but I�m totally clueless on how to replace the shaft seals and pilot bearing. The rest I can manage. I can�t find any videos on shaft seal replacements!

thanks for your help! I plan on purchasing a garagistic chassis mount short shifter soon along with a dssr and solid trans and engine mounts.

3rd gear doesn’t have a detent spring. Only 5th and reverse have it. There is some serious internal gear and/or synchro wear. I’m betting the gears for 3rd gear are shot.

What should you pay attention to when choosing engine oil?

First of all, the recommendations of the vehicle manufacturer, which refer to the appropriate API and/or SAE gradation, which is directly related to the viscosity of the oil. In addition to these recommendations, the vehicle’s operating conditions should also be taken into account when choosing the engine oil.

Are additives an integral part of motor oils and is it necessary to additionally add additives to the motor oil by vehicle users?

Additives are integral part of every motor oil and their additional addition is not necessary, because it can cause a disturbance of the oil’s characteristics. Some motor oil manufacturers even forbid adding additives to their oils due to the deterioration of their guaranteed characteristics. The oils from the LUBEX program contain the complete package of additives suitable for their classification and purpose. Any additional addition is an unnecessary financial burden for the user of LUBEX oils.

What is the role of additives?

Additives protect the engine from the created deposits by neutralizing the harmful acids that are created during the operation of the engine, provide anti-corrosion protection of the metal parts, thereby extending its life. In addition to these two basic additives, the LUBEX oils also contain additional improvers of certain characteristics such as viscosity, oxidative stability of the oil, reduction of the ability to foam and other appropriate additives according to the classification of oils that provide complete and reliable protection of the engine from all possible aspects.

Which oils are suitable for use throughout the year?

Multigrade oils are suitable for uninterrupted use throughout the year, and are recognized by the label on their packaging, such as: SAE 5W-30, SAE 0W-40, SAE 10W-40. In the marking, multigrade motor oils always have two numbers and the letter W (W-Winter). When comparing two multigrade oils, for example SAE 5W-30 and SAE 0W-40, the SAE 0W-40 oil has better driving characteristics due to the greater resistance to the influence of external temperature on changing viscosity, which means that this oil will not change its properties at higher maximum and minimum annual temperatures, unlike the other. Monograde motor oils are not suitable for year-round use, because they are much more susceptible to the influence of external temperature on the change in viscosity, and in their designation they always have either only one number or one number and the letter W: e.g. SAE 30 (summer) or SAE 5W (winter). Almost all Lubex oils are multigrade oils and their use is recommended throughout the year, which means that the user of Lubex oils has no additional costs for changing the oil with the change of seasons.

How do you recognize when the engine oil needs to be changed?

For a complete replacement of the engine oil, the recommendations regarding the replacement interval, the working time as well as the mileage of the vehicle prescribed by the vehicle manufacturer should be taken into account. The oil change may also be before the above recommendations of the manufacturer, if particles are observed on the oil level measuring tape during the manual check of the oil level in the engine. Also, the increased noise can be caused by the disturbed viscosity of the engine oil, and thus the need for its replacement. In some of the new generation vehicles, the driver receives the information about the engine oil level through the on-board computer on the information panel in the vehicle’s cabin.

What do the letters S and C mean in the designation of oils according to the API classification?

The API (American Petroleum Institute) designation for motor oils consists of at least 2 letters. The first letter in the API designation indicates the oil manufacturer’s recommendation for the use of the oil depending on the type of engine. The mark S – Service or Spark (spark) – refers to an oil recommended for use in gasoline engines where the method of ignition of the mixture in the engine is by external initialization, i.e. with a spark. The mark C – Commercial or Compression (compression) – refers to an oil recommended for use in diesel engines where the ignition method of the mixture in the engine is influenced by the high temperature that is generated during the increased compression in the engine. The second letter of the API designation represents a consecutive letter of the English alphabet that indicates the potential quality of the oil, the type of additives that are part of the oil, as well as the recommended age and equipment of the vehicle that would use that oil. The lower this letter is in the alphabet, the higher the quality of that oil and it is recommended for use in newer vehicles.

For example:
– if the oil packaging has the label: API SC, then it is an oil that is for use exclusively in gasoline engines and for older generation vehicles. In contrast, the API SJ designation indicates that the oil is for use in gasoline engines, but for newer generation vehicles.
– if there is a mark on the oil packaging: API CD, then it is an oil that is for use exclusively in diesel engines and for older generation vehicles. In contrast, the API CH-4 mark indicates that the oil is for use in diesel engines, but for newer generation vehicles.

If the API designation contains one S and one C designation (API SJ/CE), then it is a matter of universal oils that are recommended for use in both gasoline and diesel engines.
According to their labels, all Lubex oils are universal oils, which means that they can be used in all types of vehicles (gasoline and diesel) without problems. For example: Lubex Truck Plus API CI-4/SL SAE 15W-40 is a universal oil recommended for all types of vehicles of the latest generation.

What types of oils exist according to their chemical composition?

According to their chemical composition, oils are divided into three basic types: mineral, semi-synthetic and synthetic oils. Mineral oils basically contain base oil of mineral origin and additive packages according to their API and SAE gradation. Synthetic oils in their composition contain base oils that can be of mineral as well as synthetic origin and a package of appropriate additives according to their API and SAE gradation. Semi-synthetic oils are a combination of these two types of oils. In recent times, the oil industry has marketed oils of biological origin, which are still a rarity on our market. They feature biodegradable components that make them attractive in terms of environmental protection and as a potential replacement for existing oils. The oils from the Lubex program are represented by all three types of oils, such as: Mineral – Lubex Universal SAE 15W-40 , semi-synthetic – Lubex Unic Plus SAE 10W-40 and the best quality synthetic oil Lubex SuperSyn SAE 5W-40 .

Can different types of oil be mixed?

In general, regardless of its chemical composition, grade and manufacturer, it is not recommended to mix different types of motor oils because possible incompatibility and occurrence of unwanted chemical reactions may occur due to mutually different base oil and different additive packages. It can lead to the appearance of unwanted foaming of the oil, violation of the recommended viscosity, the appearance of deposits, increased corrosion, and the like. When mixing different types of oil from the same manufacturer, that danger is reduced given the fact that each manufacturer uses compatible ingredients in their oil, but even then it is not excluded. Mixing different engine oils is justified only in situations where the oil level in the engine is at such a low level that there is a risk of permanent mechanical damage to the engine. In this case, the different oil can be added, however, it should be in origin, chemical composition and gradation closest to the oil previously used in the vehicle. It is recommended as soon as possible, i.e. at the first opportunity, to completely replace the mixture created in this way with new oil according to the manufacturer’s recommendations.

What is the normal consumption of engine oil?

Depending on the type of vehicle, the driving conditions as well as the external conditions, a certain amount of oil is consumed during the operation of the engine – a part burns in the cylinders, and a small part evaporates. The oil level in the engine should be regularly checked through the oil level gauge and/or through the information panel in the vehicle cabin and promptly intervene by adding a new amount of identical oil to compensate for the consumed amount. If this phenomenon of increased oil consumption is frequent, we recommend visiting an authorized service center for the specific vehicle in order to discover the cause of this phenomenon.

Is it good to put lower quality (cheap) engine oil and change it more often?

In any case, it is good to change the oil more often, especially if the vehicle is used in start/stop city driving conditions, but at the same time it should be known that sometimes motor oils of lower quality and lower cost, although new, do not have some of the properties that quality oils have even when they are at the end of their service life. The oils from the LUBEX program do not lag behind the world-famous brands offered on the Macedonian market in terms of their quality, they are more affordable for their price and are the real choice for anyone who wants to protect their engine with quality.

Does engine oil affect fuel consumption?

In recent years, the motor oil industry has been producing oils that provide better and more durable lubrication of all mechanical parts of the engine, thus ensuring its protection. In doing so, the friction of the moving elements in the engine is reduced, which is the main reason for the loss of part of the useful energy obtained during the operation of the engine. These reduced losses of useful energy are made possible by high-quality multigrade motor oils, whereby fuel consumption can be reduced by 2-3% compared to the use of low-quality motor oils. All LUBEX oils belong to the group of quality oils that, in addition to efficient protection of the engine, ensure reduced fuel consumption.

Choose the right oil for your car’s engine

How to find out which engine oil from our Lubex family is the best for your car? It is very simple, through the markings found on the packaging of each oil. These marks refer to the classification and specification of the engine oil. Of course, first you will need to check in the manual for your car which motor oils are recommended by the vehicle manufacturer.

Viscosity class

The basic division of motor oils is done according to the viscosity class. This term refers to the fluidity of the oil. The designation is applied internationally and consists of the three letters SAE , as an abbreviation of the S ociety of A utomotive E ngineers followed by two more numerical designations and the letter W (Winter) between them. The first number refers to the viscosity, i.e. the fluidity of the oil at winter temperatures, while the second number refers to the fluidity at summer temperatures, i.e. when the engine is warmed up.

The lower the first number, the greater the fluidity of the oil in winter temperatures, and thus the ability of the oil to quickly reach the moving parts of the engine. Accordingly, a higher value of the second number in the designation means that the oil retains its ability to lubricate even at high temperatures. For example, the 5W-40 designation on our premium Lubex Supersyn motor oil means that it provides reliable and thorough engine lubrication over the entire temperature range between -35 o C and more than 40 o C.

However, the viscosity class is not the deciding factor for the quality of a particular engine oil. That’s what the specification is for.

Specification of motor oil according to ACEA and API

What qualities and properties the engine oil has, i.e. what composition and what types of engines it is intended for can be found out through the oil specification mark according to ACEA and API norms.

ACEA stands for the European Automobile Manufacturers’ Association and labels motor oils according to the following:

– ACEA class A are motor oils for gasoline engines in passenger cars
– ACEA class B are engine oils for diesel engines in passenger cars and delivery vehicles
– ACEA class C are engine oils for gasoline and diesel engines with a smoke particle filter in the exhaust system
– ACEA class E are engine oils for diesel engines in cargo vehicles

The class designation is supplemented by a numerical designation, which basically refers to the limits of the amount of sulfated ash, phosphorus and sulfur:

– ACEA A1/B1 – engine oils for reduced fuel consumption and low viscosity at winter temperatures
– ACEA A3/B3 – oil for high-performance and low-speed engines; reduced volatility and prevention of deposits; possibility of extended replacement intervals. Not intended for direct fuel injection diesels.
– ACEA A3/B4 – same as A3/B3, but intended for diesels with direct fuel injection.
– ACEA A5/B5 – engine oil with extremely high performance, for gasoline and diesel engines with direct injection; possibility of extended replacement intervals.

The specification according to the American Petroleum Institute (API) indicates the quality and properties of the oils. Marking is done with two letters after the basic API designation: S refers to oils for gasoline engines, C for diesel engines. According to this specification, they differ:

– AAPI SM – valid since 2004, with reduced fuel consumption and protection of the exhaust gas purification system.
– API SL – valid since 2001.
– API SJ – valid since 1996; reduced evaporation loss.
– – API CI-4 – valid since 2002; for engines with exhaust gas recirculation
– API CH-4 – valid since 1998

In addition to these specifications, car manufacturers set special requirements regarding the quality of motor oils with their own specifications, such as BMW, Ford, Mercedes-Benz, Opel, Peugeot, Porsche, Renault, Volkswagen, etc.

Engine oil tasks

The term “lubricant” used for oils or greases refers only to the most important function they have in the engine and in vehicles in general. With the development of automotive technology, the means of lubrication were also developed in parallel, so that over time they were improved from an ordinary working tool to a kind of “constructive part” of the engine, which contributes to its quieter operation and longer service life.
Lubrication: Lubrication reduces the friction between engine parts, and thus their wear. Accordingly, less heat is released.
Cooling: The lubricating oil receives the heat from the places which the liquid from the cooling system cannot reach, such as the pistons, and conducts it, for example to the oil pan, or in certain models, to the oil cooler.
Sealing: The lubricant performs the function of fine sealing, for example in the cylinder liners.
Suppression of noise: Through the layer of oil, the metallic sound from the moving parts, for example the pistons touching with the cylinder liners, is muffled.
Protection against aging: Additives in the oil prevent the formation of deposits in the engine in the form of resinous or asphaltic compounds.
Maintenance of cleanliness in the engine: The oil contains additions (additives) that neutralize impurities in the oil and keep them in it, thus preventing them from accumulating on the vital parts of the engine.
Corrosion protection: Through the layer of oil on the metal parts inside the engine, corrosion under the influence of condensed water and air humidity is prevented. Engine oil is also capable of absorbing a certain amount of water.
Neutralization: When reducing the degree of compression (the blow-by effect), part of the combustion gases reach the engine block. The oil neutralizes harmful ingredients, such as sulfuric acids that are created from sulfur dioxide.
Power transmission: Power is transmitted to all lubrication points through the thin layer of oil. In sliding bearings, for example, this is done through the creation of an oil wedge for lubrication.

Do you know that.

… in cars up to 1910, the driver had to pump the oil using a hand pump into the engine housing or bearings. … until 1925, drivers still had to intervene by injecting an additional amount of oil through the hand pump at higher engine loads, usually on motorcycles. … in modern high-revving engines, the flow of oil through the lubrication system is between 300 and 400 liters of oil per minute. For comparison, the blood flow in the human body, with five to six liters of blood, reaches a flow of about 100 liters per minute during strong exertion. … the temperature of the upper piston rings and their grooves reaches a temperature between 240 and 280 degrees Celsius, depending on the engine. The oil also has the task of absorbing part of this heat

The lower the first number, the greater the fluidity of the oil in winter temperatures, and thus the ability of the oil to quickly reach the moving parts of the engine. Accordingly, a higher value of the second number in the designation means that the oil retains its ability to lubricate even at high temperatures. For example, the 5W-40 designation on our premium Lubex Supersyn motor oil means that it provides reliable and thorough engine lubrication over the entire temperature range between -35 o C and more than 40 o C.

However, the viscosity class is not the deciding factor for the quality of a particular engine oil. That’s what the specification is for.

The difference between mineral and synthetic motor oils

Modern motor oils, depending on the type and efficiency, are based on a variety of base oils, i.e. their mixtures. Additives are additionally used, which through chemical and physical action improve the properties of lubricants. Only with a well-balanced formula of base oil and composition of additives can a motor oil with high efficiency be derived. The basic rule is: the higher the share of additives in the motor oil, the higher the quality and, accordingly, the price. Mineral oils are the longest used base oils. They are composed of hydrocarbon compounds of various shapes, structures and sizes. Their production is relatively simple and with lower costs, through the distillation and refining of crude oil. Most synthetic oils, just like mineral oils, are produced from crude oil, but the production process is more complicated and expensive. Unlike mineral oils, which consist of different hydrocarbon molecules, synthetic oils mostly consist of equal hydrocarbon molecules with a linear structure, which as such are not naturally created in crude oil but are the result of additional synthesis. Synthetic oils have a wider application and their uniform structure better corresponds to the efficiency of the additives, due to which special and higher quality properties can be achieved. Fully synthetic oils have several significant advantages over mineral oils: – Better starting when the engine is not warmed up and at low temperatures – Less wear due to the faster supply of oil to the lubrication points – The lubrication layer maintains stability both at higher loads and at higher temperatures. The mixture of mineral and synthetic oils in different proportions represent the so-called semi-synthetic oils.

Types of additives

Antiaging additives
Even the best quality lubricating oil is susceptible to oxidation, i.e. aging, under the influence of heat and oxygen. This creates acids and deposits in the form of resins, which usually do not dissolve in the oil. Aging is very slow in the beginning and the oil does not change. But after inactivating and neutralizing some of the additives that have the function of slowing down the aging process, the rate of oxidation increases at an accelerated pace.

Detergents and dispersants
During the combustion process in diesel and gasoline engines, a multitude of combustion products are created, which affect the engine oil to a greater or lesser extent. These are mainly products of oil aging, partially or completely unburned fuel residues, smoke, acidic compounds, nitrogen oxides and water. The task of detergent, i.e. dispersant additives, previously known as HD-additives, is to wrap solid and liquid impurities and keep them in the oil in order to prevent their deposition on engine parts. In addition, acidic compounds must be neutralized.

Additives for corrosion protection
Corrosion is basically chemical or electrochemical etching of metal surfaces. The most common causes of corrosion are oxygen and water. The water necessary for corrosion and acid formation comes primarily from moisture in the air. In a smaller amount, water appears from the combustion resulting from the reaction of the fuel with the oxygen from the air.

Anti-extreme pressure and anti-wear additives
When parts that slide against each other, such as bearings, pistons, valves and gearwheels, can no longer be completely separated under high load, the surfaces of the sliding bodies come into contact, causing increased wear and, in extreme cases, their deformation or partial melting. These additives create an extremely thin layer on the sliding surfaces. Under normal conditions, they are non-sliding, but under pressure and temperature they acquire the ability to slide. In this way, direct metal-to-metal contact, i.e. excessive wear, is prevented. As needed, these layers are constantly renewed.

Viscosity index improvers
Mineral oils change viscosity depending on temperature. At a low temperature, they are less fluid, and at a higher temperature, they are more fluid. This change in viscosity with respect to temperature can be more or less pronounced in different oils and it is expressed in a dimensionless numerical value VI – viscosity index. Monograde (single-zone) motor oils have a VI between 90 and 100, while multigrade (multi-zone) motor oils have a VI higher than 120. This value can be achieved in mineral oils with a VI between 90 and 100 by adding viscosity index improvers, which are long hydrocarbon molecules in the form of fibers. When the oil is cold, the molecules are compacted and undissolved, not affecting the increase in viscosity. When the oil is heated, they completely dissolve and swell, achieving the desired thickening of the oil, and thus a higher viscosity index.

Pour-point reduction additives
The pour-point is the lowest temperature at which the oil is still liquid. The thickening of the oil is due to the crystallization of the paraffin contained in the base oil, which also leads to an increase in viscosity. To prevent these phenomena, additives are used, which create a large number of small and unconnected crystals, which affect the fluidity of the oil to a lesser extent compared to large and connected paraffin crystals.

Antifoam additives
Moving parts, such as the crankshaft, pistons, gearwheels, etc. cause intensive mixing of the oil with the water, which leads to foaming. Foam adversely affects the full functionality of the lubrication system and can cause severe malfunctions.
