Diagnostic Aids

Check for deformed connectors at pass-thru connector. DTC 68 will set when going to default (2nd gear). An intermittent incorrect engine speed signal will set a DTC 68 if incorrect signal lasts for more than 2 seconds. A mechanical failure in 1-2 shift solenoid (stuck off) or 2-3 shift solenoid (stuck on) could set DTC 68.
