I currently have an ls1 that is need of quite a bit of money in new parts. I found a few t-56s on craigslist for a decent price. I found two for pretty cheap that were from an LT1 car, or a c5 corvette.

I know the bell housings are different from the LT1 to the LS1 and so is the input shaft. If I were to think about the corvette trans, what is different between them? I know the cases are different, but what internals would be compatible?

Corvettes have different syncros, what are you trying to replace?

Well, I need a basic rebuild, including blockers, keys, and springs.
Mainshaft
Bearings
5/6 Synchro
probably 5/6 gear cluster
5/6 driven gear

plus whatever else I find wrong with it.

much easier to get an ls1 t56 fro fbody or a gto. Lt1 needs a midplate, bell housing and input shaft. About 400-500 in parts the corvette would need even more as its made to munt on the irs in the rear

GTO T56s are M12s. he has a M6 T56 so very few of the internals will interchange. The GTO M12 is a double/triple cone synchro transmission like the Corvette and CTS-V. He is going to have to get 1 from a LS Camaro or Firebird.

true I was assuming however that if he found a gto mn12 unit he would take advtange of the better synchros and just swap over his ls1 parts lol like the bell and shift lever

yea, but if he didn't know what all is involved he might end up with a mess.

I prefer to start with a double/triple cone trans, put a SSR main shaft in it, machine the tail shaft housing, throw a TH400 yoke on it and call it a beast lol.

I was mainly looking to see if the main shafts were equivalent along with the 5/6 gear assemblies.

I think I'm just going to have to fork up the money and see if I can find a rebuilt one locally or order one in .

call up tick or tdp on here and they can get you squared away. sending in your core for a rebuild will most likely be a more cost effective option than buying one outright even if yours is truly screwed its still a core to go from
