have a 2001 dodge stratus r/t 3 liter auto 4 speed trans...I have engine light and trouble codes P0705, P0715, P0720 and P0760 coming up at the same time.. I know what each of these codes are and what part thay correspond to. My question is. What is the main problem that would cause all these codes to go off at the same time..they showed 2 times on the scanner. Symptoms are....
Shift from park to reverse is hard. When i shift into D the code lights up and just goes straight into 3rd gear..I understand trans is in Limp mode..I just have no clue on wich one of these codes would be the root of the problem ..Any help would be greatly appreciated...thank you
