t56 trans in c3
Hello. Ive been building my 77 vette since october of last year. I finally got done building my motor and put a set of 295/50r15 coopers on the back. After a few test drives, the auto 3 speed isnt going to cut it.
Im planning on swapping in a t56 tranny from a 96 lt1 camaro.
I have read about differences in input shaft length and bellhousing bolt patterns. I dont want to jump the gun and buy the trans if it wont bolt up without adapters.
Im wondering if anybody has any first hand experience with the fitment of a t56 and any issues they might have ran into.
Thanks in advance

Ive been researching this topic for a few days now, and ive seen people use adapters to bolt up a t56 to a lt1. Maybe they were using a ls1 trans? As long as the bellhousing will fit (i dont see why it wouldnt) and the input shaft is the correct length, im going to take the leap and buy it. I would buy a clutch, pressure plate and flywheel for a 96 lt1 camaro im assuming, correct?

I have searched and found a lot of information. But I never found any specific info about the different shaft lengths of the t56s. Im assuming if i buy the t56 that came out of a v8 camaro, it should work if i use the same bell housing that came on the trans.
I have however digged around some more and found that i will need a flywheel for a sbc with a 2 piece rear main seal. I have read a couple threads that used the term "conversion flywheel". Could i buy a flywheel for a sbc with a two piece rear main seal? Or would i need a different flywheel?

Spec and Centerforce both sell the conversion flywheel that you would need.
I went a different route. Here's a thread on my trans swap.

Would i use the camaro pressure plate and clutch with the conversion flywheel?
I wish i could go the same route, but im tight on funds and cant shell out the $600+ to get that kit. Ill see if i can get my hands on a decently priced conversion flywheel

If you are going to adapt the F body hydraulics youll use the pull style clutch also.
You got a 2 pc rear main seal? Need a FW that adapts them
USed Centerforce 700107 assy
Stock F body bellhousing bolts right up use the Camaro fork etc
throw at the pedal will be no more than 1" to fully disengage the clutch
May have to play with the mounting angle to get the arc right on the pedal or make a stop. Not super familiar with the C3 conversions maybe theres an easier way, some bolt kit. Bracket for the slave assy is the key bet theres one out there.
T56 has an electronic speed sender you can buy or have yours converted or use a box from say Dakota or the like
I just watch the tach til I can afford one. Uses Dextron III not gear oil
PP bolts Mc Cleod 1503 from Summit FW bolts ARP GM pilot bushing (dont use a bearing)
Awesome upgrade. Sounds complicated but really isnt .Youll love it
Had a T350 with a stall also car was just friggin boring it was missing something the T56 woke things right up and made the car exciting

I gotta search the for sale threads, maybe someone has one for sale on here that wont cost me an arm and a leg.
And i agree. I have a 2500 stall converter. Its just not as exciting as i want it to be.
Thanks for all of your help guys!

Use all Fbody trans parts (clutch slave, throw out, clutch, etc) except the flywheel as stated. Clutch master for an '85 chevy pickup which has the correct angle to mount to the firewall, but the rod will need to be modded to the clutch pedal (search the forum for other have done this). You will need a clutch line made up to attach the master to the slave. The driveshaft will need to be shortened/ balanced and you might need a different slip yoke, not sure if yours will work, the '82 vette slip yoke does.

Okay, so im planning on getting all the parts sometime this week. It looks like its going to run me roughly $1300.
There is one thing that still bothers me though- ive seen people mention extended pilot bushings. Would i need one? Or will a regular one work fine?
