Question - LS6 and T56 Transmission

I currently have a 97LT1 and a T56 Transmission in my 67 Camaro, but I have an opportunity to get a new LS6 Crate motor.

Will the LS6 match up to the 97 T56 Transmission?

Thanks

Not sure if this will help, but 4th gen Camaros with the LS1 that have the 6 speed manual are T56 trannys. Most T56 trannys will bolt up to most SBCs with some minor modifications even LS1s from the 70s. Drivelines and their length come into play, but I would suspect it would bolt right up.

Im with him, i think it should bolt right up, especially if its a new LS6 and if you already have an LT1 bolted up, all the LS engines are made to be easily interchangeable like that and as far as i know all of GM's modern muscle cars use those Tremecs so any LS engine should bolt right up easily, maybe not even any work involved but the bolting process haha, id go for it! Modern power and mileage in a classic body, thats the perfect car.

PS: Isnt Black Sunshine supposed to be a 400hp Mustang? xD

No it wont. The LT1 style T56 is setup to bolt to any early model Chevy engine (SBC/BBC) HOWEVER this changed when they went to the LS1. Doesn't bolt up the same and takes a different clutch. LS1 T56 uses a concentric slave mounted to the faceplate of the transmission itself and uses a "push" style clutch (same as just about everything). The LT1 T56 uses a bellhousing mounted external slave and utilizes a "pull" style clutch.

You can buy the stuff to convert it to work or I'm sure there is an adapter to make it work but it wont be a straight swap.

Regards,
William

This is correct if i remeber, the ls1 and lt1 t56's have different lenght input shafts if i remeber correctly too.

Will69 and Onyx are right. The LS1 T56 has a little bit longer input shaft and the bell housing is different – needs adapting. There’s a pivot for a clutch fork setup on the LT1. From my memories of this there is also a spline count difference on the early style but I don't remember. There are several kits out there for this.

you can convert your lt1 setup to ls1 setup you need.

input shaft for an ls1
front trans cover to use the hydraulic release bearing
new master cylinder with the proper line for the ls1 style throw out bearing
bellhousing for ls1
flywheel
clutch
pilot bearing

I think that is about it

I am running the Tremec T-56 six speed in my 1970 behind an LS6, best choice I ever made for that car. However, I ordered mine just for my setup, so I can't help with the swap part, but it makes my 3:83 running gear streetable/highway(able).
