T56 6 speed what is difference between LS1 - LT1 versions?
#2
The differences I have noticed while helping people pull T56's is that the LS1 front plate on the tranny has mounting provisions for the hydraulic "push" type slave cylinder, while the LT1 has the fork ball, which is not used on the LS1. The LS1 bell housing lacks the mount/studs for the slave cylinder cup, but has a cutout to access the slave cylinder bleed nut.
I am pretty sure the length of the input shaft is different.... you need to verify that, but I'm pretty sure that's the case.

I can verify that the "midplate" (front of the transmission housing) and input shaft are different (along with the bellhousing, of course). I converted a LS1 trans over for use in my LT1 application.
If you're interested, I've got a LS1 input shaft and bellhousing sitting around, both in excellent condition. Trust me that you don't want to pay dealer prices on these items.

Around '98, Tremec bought out BWA (Borg Warner Automotive), who of course owned Muncie. Production of the transmission was moved from Muncie, IN to Tremec's Mexico plant. This is when the rumors started flying about the LS1 transmissions being weaker than the LT1 versions, despite the fact that they both use the same parts manufacturered by effectively the same company.
