I rebuilt the transmission, reman torque converter, reman valve body. I pinched and repaired 4 wires during install. The trans worked great for about 20 min then got trans fault and acted like limp mode. Shut truck off restart and fine for a few minutes. It does this reliably. I replaced the tcc solenoid and no change. Could the repaired harness cause this? I have checked and rechecked the connections. Any ideas on what’s causing this or tests I could run are appreciated. 4r75e trans. Thanks.
