T-56 Transmission Install Thread

I am in (have been) in the process of a T56 swap in my '93 SC Tbird, and have found out a few things. There is a difference in the clutch adapter plate (front of Trans housing) the GM slave bolt holes clock the slave differently than the Fords and Viper units. I bought a remained unit for an Y2K LS1 Camaro. Turned out that the CAP was a Viper unit (mine is a BW Trans, not a Tremec) while the rest of the Trans was GM.

Speedo was solved by using a Dakota Digital converter.

Longer than needed input shaft can be mostly solved with a scalloped spacer between the CAP and the bell adapter (I had to use a 0.50" spacer) and longer locator pins.
Also, if a spacer plate is used, a slave shim may need to be used. Mine was about 0.40" thick (local machinist after my search netted 'no longer made, to over $50)

I used a Viper slave (it's clocked same as FoMoCo) and the Q-D was compatable.
The GM hyd. Line has a restrictor that can cause slave pump-up during rapid clutch work.

I used the LS1 due the stock shifter location being so far back.

I also used a GM pilot Brg with a bronze sleeve (made by local machinist) to fit the Blue oval crank hub.

I have changed from my path of OEM force-inducted V6 to a N/A BBF. But, with the exception of bell adapter, flywheel and clutch assy., it all transfers over.

I used the Hurst Billet shifter with my original shifter stick and knob.

Good luck
