I know you are suppose to use ATF in the t-56, but I was wondering why exactly? I have had many people try to rebuke me and tell me not to use ATF and all I can tell them is its what I was told to use. Why do you use ATF?

 

I ask the question why not? Thats what the tranny and manual calls for, thats what all the camaro gods on here call for... So thats what I put in about 3 weeks ago.

Thats all I know too. I want the technical reason for it.

 

Why would people rebuke you because you put in what the manual calls for? Sounds like they are the ones needing the rebuke.

The manual says that any other lubricant may damage the blocker ring friction material or its adhesive.

GM is not the only one using ATF in their manual trannies. I would guess that the trannies were designed to use the ATF for less drag which probably increases gas mileage.

 

Maybe I will curse myself, but I have had Mobil 1 ATF in mine for over 40k miles without any trouble.

 

People are still stuck in "old school" mode. In the old days they used gear oil. Just go with what your manual says. I think it may even say it on a yellow sticker on the left side of the trans?

 

I am out on ATF. Regardless of what the manual says. Just like the manual say to replace a craced exhaust manifold with new manifold. I would rather replace it with a header. I blew up three trannys with atf before my buddy talked me into using mtl and I have not blow up a tranny since. first 70k mile killed 3 trannys last 80k is still on the same one plus my car makes much more power then it did before. next example once again my firehawk has 80k on the last tranny. I put 3400 miles on my z06 which is lighter and makes less power and blew it all to ****. it had factory atf.

 

It's an orange sticker

Somebody ought to ask "Taner" what he uses in his M6 to make 9.60@141.52 passes I'd certainly trust his judgment.
