T-56 in 69 GTO.

joesweeting · 11-07-2012, 09:29 PM

There is a T-56 six speed for sale locally. It is attached to a V6 engine in a 94 Camaro. Any one have experience with a similar swap. I didn't see any torque or.horse power rating that differed for the V8 model and the V6 model. The car is nit matching numbers and is a daily driver.

Thanks,

Joe

Something isnt right.... In 94 the camaro used a 60 degree 3.4 v6, which is not compatible with a t56

I guess they could have put a 3.8 v6 on there, but that would be a very expensive and difficult conversion just to go from one v6 to another

Thanks for the information. I double checked the ad and that is what it states. When I called it was a salvage/auto parts company and they are expecting the car in the 16th. I will look into further. Thanks again.

There was a 6 speed in 94 that would work with an old block, but it only came with the LT1 engine. Just do you know, an LS1 era T56 will not work.

Good luck, please update this thread, I'm interested in what the salvage yard says. I'm betting it's nothing but a stock t5 behind a 3.4

Will do, I was told to call back on the 16th when it would be in.

It takes a pretty beefy transmission to survive behind a torquey Pontiac. Something designed to live behind a V6 won't last long...

I have a t5 behind my 2.8 v6 third gen camaro, and that's about all it can take. I'm seriously wondering if I'm going to do it harm to upgrade to a 3.4

A T56 designed for a LT1 should be fine. those things are pretty tough. I have friends that have put them behind some 500HP engines without a problem

Thanks, I checked Wikipedia and it stated that it can 450 lbs of torq. I have several projects on the GTO.

I bought a underdash vent system that I need to verify it fits and then paint it.

I need to find the source of the water leak around the cowl or windshield.

I need to get a new transmission yoke, I replaced the rear seal and it is still leaking.

I want to rewire my car, but I have a unique situation, I'm partially color blind.
But I'm gonna wait until after I fix the leak

I also bought new floor pans thinking it would take a while to get shipped. But I don't want to do it until I fix the leak.

Need to set the total timing.

Unfortunately, I usually only have one day to use the auto hobby shop on base.

I was looking at a T 5 the other day. It looks complely different than T56. I was told i would have to heighten the trans tunnel. And come up with slave cylinder issues. It runs an internal slave on throughout bearing. Too much work for extra gear. Also figured i would end up skipping geats to let the motor stay in its torque range.

That was if i used the T56. He wanted 1500 for it. Then how much deeper in my pocket would i have to go to male it all work.
