What Does P0982 Mean?
DTC P0982 indicates that the TCM has detected an abnormally low voltage or signal on the shift solenoid "D" control circuit. This typically means the circuit is shorted to ground or the solenoid coil has failed with a shorted winding. The transmission may exhibit stuck gears, failure to shift, or enter limp mode with a single default gear.
Common Causes
35%
Short to ground in the wiring between the TCM and shift solenoid "D"
30%
Internally shorted shift solenoid "D" coil windings
20%
Corroded or water-damaged transmission harness connector causing low-resistance path to ground
10%
Failed TCM solenoid driver circuit pulling the output low
5%
Damaged transmission internal wiring harness making contact with transmission case
Diagnostic Steps
1
Disconnect the transmission electrical connector and measure resistance of shift solenoid "D" coil; a reading significantly below specification indicates a shorted winding.
2
With the connector disconnected, check continuity between the solenoid "D" control wire and chassis ground to detect a short to ground in the external harness.
3
Inspect the transmission harness routing for areas where wires may be pinched, rubbed through, or exposed to heat from exhaust components.
4
Check the transmission connector for moisture intrusion, corroded terminals, or damaged seals that could create unintended ground paths.
5
If the external wiring tests clean, the internal transmission harness may be damaged; this typically requires valve body or transmission pan removal to inspect.

The most common cause of P0982 (Shift Solenoid "D" Control Circuit Low) is: Short to ground in the wiring between the TCM and shift solenoid "D"
Typical repair costs for P0982 range from $150 to $1,100, depending on the vehicle, location, and whether you do it yourself or go to a shop.
A stuck solenoid can lock the transmission in a single gear, reducing the driver's ability to accelerate or decelerate appropriately. This is particularly hazardous in traffic or when merging onto highways.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0982 to identify the root cause.
