I installed a new engine wiring harness. And my problem still exists. I had the tps tested at AutoZone with a actron testing tool. It failed the test. Being I don't know how these pcms work. Is it possible that the tps is giving the pcm false readings. And the pcm is grounding the torque converter solenoid circuit. Because if I press the gas a lil harder than it won't engage. Stupid weird problem.
