How about this? http://www.makcotransmissionparts.co...R-K-BOX-1.html

I have been ordering most of my parts from these folks. Some of the best prices I can find anywhere. I'm actually just finishing up a Ford C4 on the bench now and have a 700r4 next in line. Both high performance builds with parts bought from them.

Re: Rebulding Th400

what engine are you using ?

TH400s with BOP bolt pattern will not mate to a SBC.. I am sure they make an adapter plate but better off to start with Chevy bolt pattern trans.
