I have seen adapter plates for the swap, but cant find any one that has done it, or where to find info on how to. Help me if you can:scratch:
actually, chuck is right. the 200-4r is a stronger tranny. they did an article in drive! awhile back that had 3-4 tranny shops talk about overdrives and all say that the 200-4r can take more hp than the 700-r4. yes the 700 did become the 4l60e, but even then the vette got the 4l80e. the gnx cars got the 200-4r, and that car outperformed the vette. beside all that, is a slant 6 gonna kill a 700-r4???? NO.
Why go through all the hacking and headaches to wind up with a POS GM tranny, when all you have to do is bolt a Gearvendors overdrive unit to your 904 and shorten the drive shaft? You will wind up with a 6 speed auto for about the same money. Just my $.02.
To me all of the GM trannies are barely worth the aluminum they are made out of now.
