Hello everybody, recently I have had my tcm replaced after a previous issue of the car giving me a hard jolt at high speeds. That problem is solved after the tcm repair, but now I have an issue where the car refuses to shift into 5th gear. The car on the highway stays in 4th at 4K rpm and won’t budge to 5th. I plugged in the computer and the P0720 (Output speed sensor circuit) code came up. This is the only code I have. Is it the actual sensor or bad wiring? The tcm was just replaced so that is my last resort as the issue.
