84 Tranny question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

krue · 07-26-2006, 08:27 PM

My brother is piecing together a 84 p/u that the po removed the engine/tranny. Looking at the driveshaft and shifter on the column we are assuming it had a TH350 (only 3 positions on the shifter and the shaft fit in my bro's 700r4). My bro put a 700R4 out of an early 80's Caprice in it. The truck had a plug on the wiring harness that plugged into the tranny on the drivers side. After reading a thread here I think the tranny it had was a TH350C. If that's the case, will the same circuit that operated the t/c lock on the 350c work on the 700?

Im not sure if it will work or not. I would check the pin placement of the transmission plug and the wire connnector.

Yes, it should work just fine.

I would not think it would be the same and if your wrong you might burn up the switches inside tranny.

The wiring harness is identical to the one in the 83 parts truck (which had a 700r4 in it) so we're hoping we're good to go.
