I have a 97 S500 in the shop with P0715 and P0720 codes. I replaced the
connector plate in the valve body and tested the solenoids and speed
sensors. They are showing good readings from the connector with an ohmeter.
The code come back after clearing and road testing and the trans stays in
I can only read OBD II generic codes with my scan tool.
Any suggestions would be appreciated.
