Automatic Tranny Fluid in an M6?
Am I getting this right, I'm supposed to put ATF oil into my manual tranny? Seems kinda funny to me. Also, if change the oil in the rear and, how do I know if I need the additive for limited slip differentials? Thanks

Manual transmissions get oil intended for manual transmissions!!! I believe it's more like 80W90 gear oil (same as rear end)? ATF is strictly for the automatic (or power steering fluid). Also, all V8 F-bodies have a limited slip differential, so you could run the additive as well (although I don't know if you have to? ).

If you are that concerned about the additive(rear) then call the dealer. If you have a G80 rpo code on your door placard then you have a limited slip differential.And it is my understanding that you dont need the additive for a Zexel Torson unit.The Zexel unit is a worm gear drivin differentail,No clutches.The cluches are what require additive to avoid chatter in the diff.
We have the same model/year/drivetrain car and you should have the Zexel Torson T2 unit in your rear as I do. If you are that worried the additive is not that much to have ready in case you dont have a worm gear unit,which after you get the cover off will be plain as day"Ray Charles could see that".
So I say you dont need additive if you got ZT,but need a gear oil that satifies GL-5 requirements.
What happened to the Red Line synthetics you were planning? Thats the best, I'm very happy with them

Okay.... There seems to be some conflict
I bought four quarts of Red Line D4 ATF fluid earlier today for the tranny. This will work correct? It says Automatic/Manual Transmission Fluid on the bottle also. I hope this is okay because I payed more than $30 for it. I am almost positive that in the manual it says to use a Dex III grade ATF oil. So is what I got okay?

I think old manuals (like the T-10 in my dad's '73) use a gear-oil type oil. I know we had a jug around before that said specifically for "manual transmissions", but the newer ones might be using different stuff now (ie: ATF oil that's good for both).

You know Capt Pete you can benifit from this fluid & fresh filter also,it works for the autos also...pretty damn smooth.
Ferocity get the Red Line gear oil soon...you dont know when the last time it was changed and the maintenance schedule on the rear end is every 7,500miles alittle more after you switch to the synthetic thou.

There wasn't that much left on the shelf so I got it before anyone else did. Turns out Reibes does have it. There was a seperate shelf that had some other Red Line oils and I found it.
I forgot the damn gasket though. I won't be able to drive my car all week so the caliper paint can "cure". So I can get the gasket this week sometime.
Thanks for the help

my brother has an 01 ranger with a stick and it requires atf in the transmission, and i was with him one day at the dealership when he asked a mechanic why it takes atf and the mechanic said that the tolerances in between the gears and everything else is to small to allow a thicker lubricant

The T56 uses a Dextron II fluid or any fluid which carries the traits found in Dextron II. The T56 is designed to use an ATF fluid but you can also use some MTL fluids. I run Redline MTL and found it to be much smoother than the generic ATF stuff you get off the shelf. Been using it for two years now with no problems. Some people run Redline ATF and Honda ATF is also very popular as well. I will have to check but I think Honda ATF, Redline ATF, and Redline MTL all include the Dextron II traits.
From what I recall the worst thing that happens when using the wrong fluid is that it will eat away at the syncros which I think only applies to aftermarket carbon syncros. If you want to run carbon syncros in your T56 you should be careful as to what type of fluid you use.
