I have a 1989 K-5 that had the TBI-350 SBC and a TH700R4 tranny with the NP208 Transfer case installed when I purchasd it. All that is gone and I have installed my Built 350 SBC ,Carberated (Holley Street Avenger) with a TH400 and NP208, Now here is the Dumb Question, The kick down wire that is connected to the L/H side of the transmission,"single wire connection" where is this supposed to hook up to, recently smoked the tranny and truely believe this was the culprit, after a $1000.00 bucks in parts and labor and hours of cursing and sweating to remove and reinstall, I just want to make davvn sure it is hooked up correctly. 1st "Where is the wire supposed to be connected to?" 2nd "Does it receive constant power to the sensor or only after start up?" 3rd " Any one else have a simular transmission failure?" Thanks and if you ever make it to South Korea I got the first round.
