Need transmission help how to wire up a 700r4.
I just traded for a dually that was originally a diesel with,I think a 4l60e. Truck now has a crate 454 and a 700r4 and when the swap was done,they didnt hook up any wiring to the trans. Speedometer doesnt work of course,but what I am worried about is the torque converter doesnt lock up and the transmission doesnt shift correctly. Can anyone tell me how to wire in the 700r4 to the trucks harness or is there an aftermarket adapter that I can get? Thanks in advance for any help.
