Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information TCM-P082601

Condition




On the circuit board for the gear selector module (GSM) three Hall sensors. A permanent magnet on the gear lever affects the sensor output signals to the gear selector module (GSM). When the gear selector is moved to manual position " Man", the automatic transmission will still be hydraulic in position D, but by moving the gear selector upwards (+) the gear selector module (GSM) will send a signal to the transmission control module (TCM) to engage a higher gear. Moving the gear selector downwards (-) sends a signal from the gear selector module (GSM) to the transmission control module (TCM) to engage a lower gear. If the gear selector module (GSM) registers that the signals from the gear selector do not agree with the " Man" position, the diagnostic travel code (DTC) is generated.
The diagnostic trouble code can be diagnosed when the ignition is on.

Substitute value
- No manual " Man" gear changing.

Possible source
- Gear selector module (GSM) not working.

Fault symptom[s]
- Changes gear according to D in " Man" position.
- No gear changing.
