Why am I getting this code P0752/P0758

Question

I just bought a 2001, Rav4 150K Miles.  Engine light came on showing error code P0752.  I checked online saying the transmission fluid might be dirty and blocking the valves. Car runs great on flat surface, changing gears normally.  I still did a transmission fluid service (change the transmission fluid) and a full service Oil and filters.  Engine light stayed on.  I am now getting code P0758.  The cars changes gears normally, why am I still getting these error codes?

Please advise.

Answer 1

P0752 Shift solenoid A performance or stuck off / 1-2 shift solenoid valve performance

P0758 Shift solenoid B electrical / 2-3 shift solenoid circuit electrical

This code had to make this year make and model Rav4 famous what happen is the ECM was reprogrammed to solve this problem. regardless if the shift solenoid is within specification replace the shift solenoid, being a solenoid it can short out its driver located in the ECM. and do not be surprised if the ECM would need to be replaced.
