T-56 Questions

[Shifty_Capone]

Don't know much about T-56's but I've got a super good deal on one coming my way and I need to know if it will bolt up to a BBC specifically my 396 that I'm putting in my bro's 67 Camaro.

Did a little searching on other forums and found nothing, anything that'll point me in the right direction will be awesome!

thanx - Erik

i believe if you get a T56 set up to run behind a lt1 that it should bolt up to your BBC i believe they were different for the lsx motors but dont quote me on that

That's right. THe LT1 T56's have a SBC bellhousing pattern. The LS1 transmissions are different.

Has something to do with the input shaft length, doesn't it? The bellhousing bolt pattern for the LSx doesn't use one of the bolts, otherwise is the same as the "traditional" Chevy V8 bolt pattern.

From what I understand. . .

LT1 t56's will work fine, LSx T56's have what looks more like a BOP pattern and will not work. The LT1 t56 is good for about 500ftlbs in LT1 form, if you are making that much or mark and have a heavy car or one that sticks really hard you will need upgraded main and output shafts.

Differences between the '93-'97 f-body, 98+ f-body, and Aftermarket T56
1993 to 1997 LT1 F-body T56
Same length as T5 and 700R4, so you can re-use your same 27 spline driveshaft, torque arm, and bushings
Electric 40 pulse per driveshaft rotation VSS (Vehicle Speed Sensor)
LT1 pull-style clutch, bellhousing, and slave cylinder is necessary
1998+ LS1 F-body T56
This is from the LS1 f-body, so it has a different length input shaft, and a completely different push-style clutch setup. The throwout bearing is a hydraulic unit that eliminates the clutch fork. To change this transmission to work with the LT1 clutch and bellhousing, you will need to replace the input shaft as well as the front cover of the transmission case (because it does not have the clutch fork pivot). An LS1 master cylinder might be necessary. The case and tailhousing dimensions are identical to the LT1 T56.
