Getrag 260/6 oil type

[HandalE30]

Hi, I have a getrag 260/6 gearbox (cooling fins) from an 1991 e34, but have always seen different answers on the web about the oil it should use. My gearbox does NOT have a sticker on it but dont know if it fell (which im told its not probable) and the drain screw is different than the getrag 260/5 in my E30 325i it does not have a head. dont know if I have to use dexron II,III or redline MTF or any other. Please help on advice Thanks!

I use Redline in all of my transmissions and the feel is excellent. I have seen ATF recommended for the 260/6, but I would confirm this first since it's some pretty nasty stuff... Redline MTL is pretty darn thin. I prefer the Redline 75W90NS, it is supposed to be great for older syncros (we sell it for Alfas) and it's quite a bit heavier than the MTL.

I just used some regular synthetic ATF for mine...

I think Im going to try out Swepco 201..its really thick though..might be an issue when its cold :???:

heres what I took from BMW operating fluids manual, check 3.0




1.0 General Information on Gear Lubricants

Gear lubricants for manual transmissions must conform to the following requirements due to the different transmission designs with considerable variation in loads, temperature and speeds.

The qualities of a recommended gear lubricant are:

A. Load carrying capacity, i.e. high-pressure resistance.

B. Noise reduction.

C. Non-corrosive to various metals.

D. Non-foaming.

E. Non-separation of additives at operating temperatures.

F. Non-sludge forming.

G. Prevention of swelling, hardening and shrinking of seals.

These properties are already provided in manual transmission oil by:

— High-pressure additives.

— Corrosion inhibitors.

— Oxidation inhibitors (inhibitors which limit or prevent chemical reactions).

— Anti-foaming agents.


2.0 Oil Additives

BMW manual transmissions are designed so that they do not require aftermarket oil additives.

BMW disapproves the use of any oil additives and cannot accept the liability for any consequential damage that results from using oil additives.


3.0 Manual Transmission Oil Requirements and Specifications


A. All reputable brand mineral-based transmission oils of viscosity class SAE 80 according to specifications MIL-L-2105 or API GL-4 (no label on transmission bell housing).

B. Synthetic transmission fluid, Mobil SHC 630 (325e/528e without dual mass flywheel, produced before mid-1986).
Manual transmissions which are filled with Mobil SHC 630 synthetic gear lube have a green label with the words
“Special Oil” located next to the oil filter plug.



Note: Mobil SHC 630 is available in 5-gallon pails or 55-gallon drums from:

Mobil Oil Corporation - Contact your local Mobil oil distributor (see Yellow Pages) or call 1-800-582-3645.

Filling BMW transmissions with unapproved synthetic gear lubes could cause the following damage:

— Premature synchromesh ring wear
— Reduced service life of bearings
— Tooth profile damage
— Faster wear of selector forks
— Damage to radial shaft oil seals

Transmission gear clashing will eventually result.

Note: Do not use synthetic fluid Mobil SHC 630 in other vehicles. The transmission synchronizers of cars other than listed above are not compatible with synthetic fluid and premature wear will result.

Note: To reduce the physical effort required to change gear at low ambient temperatures, the following oils can be used in the transmission during the winter:

— Single-grade HD mineral engine oils SAE40, SAE30, SAE20
— In countries where the ambient temperatures are particularly low, ATF oils can also be used.

This has the disadvantage that the transmission tends to rattle or knock while in neutral at higher temperatures.

CAUTION! These transmissions must never be filled with synthetic engine oils or multigrade engine oils, since these oils contain coefficient of friction-reducing agents that can adversely affect operation of the synchromesh mechanism.

C. Automatic Transmission Fluid (ATF) of Dexron® II or Dexron® III formulation on any of the following:

— Dual mass flywheel
— Direct drive fifth gear as of 9/90
— Six-speeds

Manual transmissions which are filled with ATF have 17mm external hex plugs in the filler and drain openings as well as an orange label on the transmission bell housing next to the filler plug.





D. From model year 1998 (9/97 production) all manual transmissions are filled with Esso/Exxon “MTF-LT-1” long-term fluid.
A yellow label with the letters “MTF-LT-1” is located next to the oil filler plug.

:nice:

So E30 kid89 uses atf, Euroshark uses redline non synthetic, and BoostMW (thanks for the info there) I dont have a label on my GB so that means i would have to use option ¨a¨ (mineral based) but I also have a double mass flywheel so I would have to use option ¨C¨ which is ATF :S still confused.

I would use a good sae 80 non synthetic gear oil
