GTO Trans in Fbody? Anyone know the difference? I have an oppurtunity to get one cheap and I heard there were improvements for the GTO trans. Ratios different?
Anybody know if they are improved and what it takes to drop one in an fbody?
Thanks
Chris

The MM6/M12 specs are here

Yeah its an upgrade, but unless your T56 needs an overhaul I probably wouldn't go though the effort, but if your getting a smoking deal it might be worth it. Don rebuilt many a T56 as well, just an FYI.
The M12 is arguably the best t56 you can get. Here are the ratios btw
Your T56 2.66:1 1.78:1 1.30:1 1.00:1 0.74:1 0.50:1
GTO M12 2.97:1 2.07:1 1.43:1 1.00:1 0.84:1 0.57:1

i had it in my ta for 2 years w/ 4.10s i loved it but needed something alittle more beefier.
w/ 26" tires i would run through the gears fast and shift into 4th a tick before the 1/8 and 4th would take me through the traps at 6800
so nice!!
yes you will need the little shifter cup thing from a fbody, i have nothing bad to say about the mn12 in a fbody

LOL I guess the automatic guy will help you out again
Yeah just swap the one from your current t56
M12 comes with the big one, just swap in your smaller one.
BTW what gears do you have? If you got like 4.10's, just be prepared to get a good right arm workout.

Just went the other way and put a faceplated t56 from an f body into my gto. All i swapped were the shifter cups. The car gets better gas mileage now, in 6th at 80 i am at like 1700 rpm's, i need to add some gear!
Out of curiosity, does the GTO T56 have provisions for the torque arm mount, or would you have to swap tailshafts with an FBody T56 (or alternatively go with a chasis mount)?
