ECM uses signal from No. 1 vehicle speed sensor to determine actual gear position. ECM compares actual gear with shift schedule in memory to detect mechanical trouble of solenoids and/or valve body. DTC is set if, during normal driving, gear required by ECM does not match actual gear after 2 trips have been completed. Possible causes are:
- No. 1 and/or No. 2 solenoid is stuck open or closed.
- Valve body is clogged or valve(s) is stuck.
