ok folks..I have been a member fo this forum for a few years. I have asked many questions and received some great help....I have done about as much as you can without taking the body off.....just finished the rear gear swap out this weekend. Still waiting for the motor. Have a 700R4 in the crate (thanks to FourthGear) and hopefully based on the feedback I got, should be able to plug in the TCC harness and have lockup in 4th gear (still not sure about this), but will find out soon enough.....PS...if you don't have to change the heater core...don't do it
Does anyone have a wiring diagram of the 81 TCC harness/ECM
