Thank you.

The code P0720 is for the Revolution Sensor on the transmission. This sensor can cause the Cruise control not to work properly and cause the P1574 code. So you want to focus on the revolution sensor on the transmission. Diagnostics to verify it's the sensor starts at around 1 hour labor. Then the cost of the sensor which is around 90 bucks and 1/2 hour labor.

Do you have any more questions on this?
