93 4.3 CPI swapped into a Toyota

It took me a month of troubleshooting to figure out the VSS /Buffer signal to get my swap working right. I relocated it from the tcase to the tail housing with the advanced adapters kit. Welp, the tail housing cracked like an egg right where I drilled the sensor on my first outing.

So I'm not messing with this anymore and my good buddy runs a 700R4 in his rig behind an LS and is super happy with it. I'm going to throw a full manual valve body in the 700R4 and ditch the TV cable. What do I need to do to the PCM to make it not freak out when it looses all coms with the trans?
