If so what needs to be done? As always any links to this information are appreciated.

The only part electrical was the lockup conv. I used a vacuum switch from a late 80s van & hooked it up to ported vacuum. I also used a 2 prong oil pressure switch in the 4th gear service port. This makes it fully automatic & real smooth. The throttle cable is real critical on these. There is plenty of info if you do a search & some past posts on this websight.
