Diagnostic Aids

If the DTC is cleared, then will not reset when the vehicle is driven, some of the following conditions may exist:

• Fluid contamination
• Plugged fluid circuits
• Restricted fluid circuits
• Inspect transmission fluid lines to radiator. Lines may be pinched, plugged or twisted.
• Internal damage to the torque converter may prevent TCC application.
• It is possible for an internal TCM failure which may not allow sufficient current to operate the solenoids. Verify TCM functionality by commanding the suspected solenoid ON/OFF using the scan tool and listen for a click.
