T56 swap
Has anybody swapped out their old tranny for a T56. Where did you buy your parts, what problems did you run into, How hard was it.
|
If you are talking about a T56 from a Camaro or Firebird, as far as I know it won't bolt up to an older engine. You can take a look at the Keisler website to get an idea of the parts needed to put a 5-speed into a C3. Not an easy or inexpensive swap.

T56 Swap
I have a T56 in my 76 Vette and it's the best investment I've made. I admit I didn't do the actual swap myself, I researched everything for two years and have book of material from other people that did it. I purchased a T56 out of a local trading paper, I was told it came from a 97 camaro. I checked around to several shops and transmission places and found a fairly young guy who owned his own shop and said he would be interested in doing it, but would only work on it when he had time so I had to leave it on his back rack for almost two months. I purchased the adapter plate and longer input shaft from Fortes Parts, this allowed me to use the existing mechanical clutch setup. He shortened the drive shaft and cut out the crossmember extended it out and welded it back in. (see photos) I also had him rebuild it and upgrade to the steel shift fork. I do have a GM Crate Motor in my car, but by utilizing the adapter plate you can utilize on the older 350.
My Trans $900 Rebuild, Parts, Labor and installation $1200 http://i128.photobucket.com/albums/p...teT56006-1.jpg http://i128.photobucket.com/albums/p...etteT56023.jpg http://i128.photobucket.com/albums/p...etteT56023.jpg http://i128.photobucket.com/albums/p...teT56028-1.jpg http://i128.photobucket.com/albums/p...etteT56046.jpg http://i128.photobucket.com/albums/p...etteT56041.jpg |
72LS1Vette is confused.
You need one from an LT1 engine (93-97) Camaro or Trans Am. You need Centerforce flywheel part number 700107 (I think) to bolt to your old engine and the new LT1 clutch setup. Do a search, I did it. Many others have also. I did a write up some time ago. |
I have looked at keisler's website they offer kits for both the T5 and T56 however they are not currently making the 6 speeds. Thanks for the pictures, gives me some ideas, only thing is I want to keep my console pretty much stock (sleeper)

You can go to Fortesparts.com to check out the adapter plate, call him if needed. If you purchase the adapter plate and extended input shaft you don't have to touch the clutch or fly wheel. The adapter plate attaches to the bellhousing and once the longer input shaft is installed you bolt up the trans to the adapter plate. My T56 did come from a 97 LT1 camaro.
As far as the shifter location, I had no choice but to alter my console but I did try to resolve that. I know that the Viper T56 had available an offset shifter plate and looks as though it would come close to the original shifter. I ordered the shift plate for my T56 but the viper T56 was different and it wouldn't work on mine, so I returned it and purchased the offset shifter handel that is covered by the shift boot, this just moved the shifter forward enough to avoid the ebrake. |

I guess I should have qualified my statement further. I believe that a T56 from a LS1 Camaro or Firebird will not bolt on to an older engine. I wasn't aware that the T56 was available on the LT1 engines.

Has anyone installed the viper tranny I heard the input shaft was bigger and needs to be milled

Heres some pics .. pretty simple and easy viper core T56, with off-set McLeod shifter fits perfectly in the stock counsel.

"viper core T56" did you rebuild it or are you just saying it was a viper tranny? If you rebuilt it did you use viper internals or opt for the less expensive f-body/vette internals. Did you use the viper input shaft?

Its a GForce T56 6spd race tranny, viper core custom built by GForce with all their upgrades capable of withstanding 1300hp. They also make cross member brackets similar to what I have (mine was custom) they re patterned my bell housing to accommodate the T56 or you can buy one from them. You can check them out at www.gforcetransmissions.com or www.ddperformance.com |

if you use a T56 from a 93-97 f-body (w/LT1), the shifter is not that far from stock location.
http://www.v8spirit.com/temp/P1030076.JPG http://www.v8spirit.com/temp/P1030079.JPG from what I mesured, we need the shifter moved 2" left and 1.8" forward. |
What yoke is everybody using with the T56 from a 93-97 f-body (w/LT1)? Is there one with caps for easy removal?
Thanks. Pete |

I used a stock modified viper trans with a viper shift, it will but the shifter back almost in the stock location. I used a lakewood bellhousing , i dont remember having to do much to the tunnel, but did mod the crossmember, it's been 2-3 yrs ago I did it

Auto conversion question
Anyone converted a C3 auto car to the T56? If so, what pedal and hydraulic clutch did you use?
