I was mainly concerned with me going from a manual to an automatic, which I do not want. Do the T2 transmissions bolt up. I would assume that they would because I was under the impression that the 13B and 20B housings are all the same bolt patterns. But if I was misinformed, then I would be incorrect.

4 out of the 5 bolts will bolt up properly.

What about the counter weights. Do you have to do anything with those.

you have to buy a light weight flywheel and bolt it up to the cosmo couter wieght, there is no stock flywheel that works on a 3 rotor

Excellent, thanks.

huh?? not true! You can bolt a S5 tranny to a S4 motor. the flywheel is for balancing of the rotating assembly. IE< if you are using a S4 turbo motor, with FD rotors, you need to use S5 or FD flywheel. tranny has nothing to do with it

I'd use some american racing auto trans and go through the hard work of getting an adapter plate made.
