T-56 Transmission Install Thread

So, just to make sure...

LS1 T56 has 8.25" bell depth

Challenger TR6060 has 7.3" bell depth

Bells can be swapped to each other

Mopar oem bell is quite reasonably priced. Anyone has used that on 3gen Hemi & LS1 T56 swap?

I need to take my gearbox apart and maybe dont mind if need to shorten input shaft.

Does Quicktime bellhousing need check /re-adjust their centering?

Along with the factory bell being a passenger side starter, it's also quite large and uses the 143 tooth flywheel. I went the Quicktime route on my swap to keep the 10.5" clutch in the hopes of limiting sheet metal mods. In the end I still pretty much had to cut all the way up to the pinch weld on the firewall and floorpan and take out that piece in case I ever felt like removing the bellhousing again (it would make bolt access near impossible if the pinch weld seam was still there once the floorpan was installed.

I used a transmission directly out of a Viper with no mods other than shortening the input shaft a little. I measured it all out to be sure and ended up taking off around 0.5" as I recall. Part of this is because I'm running a register style pilot bushing. If the crank was actually drilled for an input shaft I probably wouldn't have needed to shorten things.

In regards to centering, several people have said that it was a good idea and that they found their's off some, but I just went with what I had. It's a hard piece to measure to begin with due to the odd flange on the bellhousing for the T56, but I also have a fairly mild combination, so I'm not real worried. Things have held together just fine so far and it's definitely made the drive more enjoyable. Lots of work stuffing it all in, but the first time you click it into one of the two overdrives it's worth it. Still not seeing the gas mileage I was hoping for, but have been messing with the tune to see if I can't fix that.
