P0720 2001 NISSAN MAXIMA - What is the likely problem with my car?

Question

Periodically my 2001 Nissan Maxima appears to get stuck in one gear and the car starts slowing down and sounds strained when I press on the gas. I usually have enough power to pull over and once I shut the engine off for about 10-15 mins, the car drives smoothly without any indication there was a problem. This usually happens at least once a week, more if I drive the car for several miles. I have taken the car to a transmission shop and he thought my transmission was fine. He advised me to get a complete tune up and to change the Airflow sensor. I did this but the problem persists. I took the car to Pet Boys on Saturday I got a diagnostic reading of P0720.

Answer 1

 

usually replacing the revolution sensor takes care of the problem, it is probably the first thing to do the other possible causes are

- Sensor circuit is open or shorted 
- Revolution sensor 
- Damaged ECM 
- Damaged Transmission Control Module (TCM)
