Hi everyone,

Just wondering if someone can help me out here with the Gearbox Oil.

My car is now done 64k and I wanted to replace the gearbox oil.

Went to Mini Dealer and they were useless they don't know what oil is inside the gearbox!

and they wanted £150 to replace the gearbox oil even though its about 20 minutes job

Anyway can someone tell me what Oil please the car gearbox uses ?

Thanks

put 2 bottles of redline MTL in there. job done.

Many Thanks Mate,

I want to put BMW oil in there any ideas what they use?
Why? I think from memory its Texaco MT-90 or something or other. Not easy to get hold of which is why people use different brands. As long as its the same GL rating (GL4) and viscosity its fine. Hence why i suggested Redline MTL as a lot of people use it including me and love it.

Yeah I know but I prefer to keep it to BMW Parts.

On BMW System its showing either MTF 94 or MTF-LT-1, MTF-LT-2 or MTF-LT-3

Anyway I can find what oil it has

Its a 53 Reg

I know if you have the dif like my JCW you need to put MTF 94 in. BMW only sell this in 5 gallon units and it costs a fortune from them. Do what I did ad go to your local LandRover dealer, they use it for the old freelander or something. 1Lt container about £7. Part number is STC 9158. You'll need about 1.5lt I think.

I remember someone mentioning the landrover thing too but they were after oil for the Midlands 5-spd. Not sure if those and the Getrag 6-spd's use the same oil. I wouldn't have thought so.

P.S. you need 2ltrs.
Castrol smx s
be carefull, if you have a LSD you need to get Texaco MTF-94! not sure bout a non LSD tbh.

If you need MTF-94 you can get it from Landrover as ****** said (Part Number STC 9158) in 1lts bottles (BMW only sell it in a 5Gl container go figure!!). and yeah 2lts will do her grand (again as ****** said)

Keep her lit, and between the ditches

No you dont, SMX S is just fine
How can you love a tranny oil haha.
because its red and noticeably improved the cooper's midlands

P.S regarding the Texaco MTF-94, I've been running the redline stuff with LSD with no problems. i don't get the chewbacca sounds when pulling away when cold anymore
so any feedback on before and after change,
shifts better or not
did the oil look like it needed a refresh?

sorry ****** but i want to know about posh 05 boxes,
rather than the midlands box of shame
I've got it in my 6spd too. Didn't really notice much difference in this one compared to the Midlands, not quite as stiff during the colder months (as you know 1st to 2nd can be a bastard in the winter) and I don't get the gearbox chatter I was getting with the stock fluid but overall not much improvement.

IMO I would say keep the stock stuff in the 6spd's as its quality stuff but if its difficult to get hold of the stock texaco stuff or too expensive any of the other MTF's are good (Redline MTL, Castrol SMX-S etc).
The TIS service instruction is clear about this.
Cars with the optional LSD Texaco MTF-94
Cars without the LSD MTF-LT-3
The Texaco is a GL-4 75W-80 oil, so any other with similar specs will do. I have used both Red Line MTL and MT90, MTL was very smooth on cold starts but could feel it getting too hot after long spirited drives, the MT90 takes a few minutes to warm up and then it's perfect, no signs of overheating. This time i am going to to run a 50/50 mix of MT90/MTL.
I've just swapped out my gearbox oil for Carlube MTF94 which is what BMW use for the Mini. Can't tell much difference just yet but not had a "spirited" drive as yet. Bought on an auction site for a great price and delivered next day.

Was a simple job once I had the car up and level on the axle stands.

I've used this too, £7 litre from GSF.

Old oil looked pretty clean after 65k tbh.
