Does ap2 trans bolt up to ap1 motor? Or is there other stuff you have to do first? I believe I just blew my trans

 

Yes its a direct bolt on.

You will need to change the flange on the back of the trans. Use your AP1 flange.

your speedo will be slightly off...a yellow box will fix that right up.

I have an ap2 trans in my car. nice mod.

 

A lot different from ap1? My car will go in gear and roll it just grinds like a you kno what

 

Ha!

Its not your trans. you have a broken axle. check your rear driveshaft boots, see if one is twisted up. If so, the spider is broken inside.

 

I'll bet the drivers side inner boot is twisted.
