There is a complete T/A with a T56 available that I would love to go get tomorrow, but it is a 93 and I am not well versed on them as a swap tranny in a B body. I understand they are geared different and rated for a bit less HP, but I'm wondering if anyone has any real world experience?

This would be going into a box Caprice project. From what I have read 3.73 gears is the way to go, but will this thing stand up to a healthy 350-375 HP LT1? I want a fast 0-60 and could care less about anything after that, other than that the 3.73 and 6 speed should work out to pretty nice highway cruising mileage...

Thanks,

Doug

It has a lower torque rating, but has a desirable gearset IF it is the optional M29 93-only tranny. Wink It's 3.73-friendly, too. So you most likely won't have to worry about vibrations.

Either way, I would run one in my shit. Smile

There were two different trannys for '93.

I found this:
1993 Manual/M28 3.36 2.07 1.35 1.00 0.80 0.62
1993 Manual/M29 2.97 2.07 1.43 1.00 0.80 0.62
1994 Manual/MN6 2.66 1.78 1.30 1.00 0.74 0.50

I'll leave it up to the reader to determine what the casting numbers are for each. Smile

If it's a good price grab it!

Thanks guys, so what is the deal with the M28? Assuming it is not the M29 is it worth my time?

I assume M29 would be on the spid label? Am I correct to assume it is on the trunk on these like our cars?

Yes M29 or M28 should be on the SPID label.

If you decide to pass let me know. I'd also risk the lower torque rating. 'sides I have some other lighter weight projects in mind.
