P0720, P0731, P0736, P0790 Chrysler - SEBRING 2.7L

Question

I had a transmission shop replace the input & output sensor that is in the transmission and nothing worked. The changed the fluid and filter and nothing happened. I've personally looked at all the plugs and sensors to check for corrosion and to make sure they were all plugged in. Does anyone have any troubleshooting tips?

Answer 1

P0720 Output speed sensor error

P0731 Gear ratio error is 1st

P0736 Gear ratio error in reverse

P0790 Normal/performance switch malfunction

The shop should be able to look at the clutch index with their scan tool.Because with code 1st gear error and reverse error, a rebuild should be the option. This transmission has a pressure problem.
