I had a 1991 V6 Auto tranny engine in my car
I bought a 1987 350TPI 700R4auto tranny, Wiring + Computer(complete setup)

Completed the swap got just about everything to work, had to repin a lot of things and follow a ton of schemadics but completed it with the help of big lou....

only problem i have now is my speedohmeter... i know that off the speed sensor i am supposed to bring one wire to ground and the other goes back to both the ecm and the c207 connector or something to that matter.... dont recall off the top of my head... but i have tried it, and still nothing, now i had talked to tpi hearse and he said something about the v6 having a speed buffer? and the v8 tpi engines do not have a speed buffer and it could be because of that? anyone have any ideas for me? or have completed the swap and got their speedohmeter working?
thanks a lot in advance and for your time

 

Call me right now, I'm at home, looking through the schematics.

I'll PM ya my number again in case you don't have it.
