People weld cast heads all the time.. could I get away with welding large portions of a transmission case? (902) I have a wacky idea that just might work...
you can weld up engine cases....so i cant see why not.
interested in what your doing..... 902's had a thin intermediate plate....and a big heavy case.
spill it royce - whatchu doin?

i wanted to build a 914 trans using an AL case too...
bolt patterns and stuff are different on the intermediate plate (im told - havent confirmed) and that the Ring gear cant be flipped (im told - havent confirmed)
you are doing a lot of beefing up for a v8.....
you should be fine with a cooler and./or a Billet int plate......

bolt pattern - i mean the sideshifter nosecone wont fit.
Why not just use the Audi gearbox?
As far as welding cast aluminum, yes you could weld that and probably not have any problems. I would use a 4043 rod and preheat the tranny to at least 350. You should clean it really well and do not run a continous bead. Weld a little then roatate the piece, weld some more, then put it back in the oven to even out the heat. This will take a very long time to do, then you will have to have a way to machine it parallel with the other side cover. If not you will creat all kinds of issues.
You will still suffer from the problems that plague the tranny in High HP applications. The pinion doesn't have enough support for high torque loads and the ring gear is too small.

Iffin there is any heat treat on that tranny it's going to go bye-bye at the weld area.
T-6 precipitation hardening goes to T-0 (annealed).
Not sure if the tranny has any heat treating, but most aluminum car parts do as T-0 is pretty soft.
