Texaco MTF-94 has a viscosity of about 10.5 (at 100C) with a hearty detergent and ZDDP anti-wear additive package.
It's available in 20 liter cans.
It's used Midlands transmissions, early 1st gen with Getrag, and later Getrag with LSD.
Redline's MTL is quite similar and a good substitute.
BMW-MTF-LT-3 has a viscosity of about 6 with much less additives - it's actually more like an ATF (automatic transmission fluid)
and Redline says their D6 ATF is a good substitute for it. It's too thin for the LSD to perform correctly and is used in later
1st gen Getrags without LSD. You can get LT-3 in 5 liter cans.
Both are GL-4. The sulfur additives in GL-5 oils corrode yellow metal parts like brass synchro rings and bushings in
You could probably use Texaco MTF-94 in a gen 1 MCS with Getrag without LSD, but it might shift a little harder and might cost you 1, maybe 2 mpg.
From what I could tell the Fuchs Sintofluid 75W80 has a viscosity of 9.4 - much closer to MTF-94 than to LT-3, but they seem to be saying it's a replacement for either.
I'm not sure I buy that. They list BMW application reccomendations but not MINI specific ones. http://www.opieoils.co.uk/p-981-fuch...ion-fluid.aspx
Amsoil has a gear oil with about the same viscosity (9.6) - they recommend it to replace MTF-94 but not LT-3.
When my leaking right output seal was replaced and my independent shop refilled the transmission fluid,
they gave the MINI dealer my VIN and they verified the OEM fluid to use (MTF-94 for me), then they sent the
WRONG fluid (LT-3 instead of MTF-94) in an unlabeled container*.
I noticed a different feel in the shifter and 1-2 better mpg and had the fluid analyzed, which showed
it to be the wrong fluid. About 1,000 miles later, after discovering this, I had them change it again,
and sent an aliquot of the fluid they used for analysis again. This time, it was the right fluid.
Turns out it takes a bit of effort to eliminate any doubt.
* The dealer gets MTF-94 in 20 liter containers and LT-3 in 5 liter containers, so when they send
some out to a shop or customer, it goes in a blank unlabeled quart container. You have to trust
they give you the right stuff, and that everybody keeps track of what fluid is what, and apparently, sometimes, they don't.
I've got a 53 reg Cooper S with a 6 speed box with a JCW mod. I want to change the transmission fluid (I've changed everything else) so I've been reading this thread and other information on the web.
I would have thought that my car has an early getrag gearbox so should use MTF94 fluid. I phoned the stealers to confirm this and after a lengthy discussion with the guy in the parts department (regarding the "lifetime" characteristics of the fluid) I eventually got the oil specification from him (after he spoke to the service department). He said that I should use MTF-LT-3 in my gearbox - he quoted £100 for 5 litres. I said I thought that was a ridiculous price and thanked him for his time.
I now have conflicting information regarding the specification of the Manual Transmission Fluid, does anyone know how to get a definitive specification?
Look at the document in the attachment of post # 5. This comes from the BMW MINI TIS issued 12/2007.
It calls for MTF-94 in a 2003 MCS. It's possible that MINI has changed their recommendation since then,
(maybe they're now recommending LT-3 for better mileage and cold shifting, but I've not seen that officially
published anywhere), or that your car has had a newer transmission installed to replace a failed one if you're
not the original owner.
Hi, Im looking to change my gearbox oil, but getting garage to do it and not sure can trust them to put the right stuff in. So I want to buy the oil for them first. Its a mini cooper first gen, 51 reg, 5 speed, midlands poop box. So I was thinking of getting the redline MTL, but have no idea how much or where to get it? Anyone get any links online and how many litres to get? I was looking at this: Red Line MTL Gearbox & Diff Oil 946ml - FREE P+P | eBay but not sure if thats just a little tiny amount?
Call a couple more dealers and tell them the build date and VIN of you car and ask them
what spec transmission fluid is correct. Or even call the first dealer and talk to a different person.
I'll bet they don't all give the same answer (I think a magic 8 ball is involved when you ask
as service rep).
