Sorry it took so long to get back with you. I got a diagnostic check and ended up throwing 11 codes. One says Torque converter clutch enable circuit. Another says Torque converter clutch PWM solenoid electrical fault. The others say 1-2 shift solenoid valve performance, 2-3 shift solenoid valve performance and 3-2 shift solenoid. But could those last three be from me manually shifting my automatic transmission and accidentally skipping gears and then down shifting back into the proper gear?
And anothet issue, my 4x4 stopped working, its thr push button, with the updated 5 pin, so I bought a brand new one and it didnt work, so I cut the ground wires and tested the 4x4 wires, and it took test lights, but didnt work when hooked up to a battery, so I put it in my buddies truck and it worked great, but still doesnt work in mine? Any ideas?
