What Does P0981 Mean?
DTC P0981 indicates that the Transmission Control Module (TCM) has detected a range or performance issue with the shift solenoid "D" control circuit. The solenoid is not responding within the expected parameters for commanded gear shifts. This can manifest as harsh or delayed shifts, slipping between gears, or the transmission defaulting to a limp mode with limited gear availability.
Common Causes
30%
Faulty shift solenoid "D" with internal mechanical or electrical degradation
25%
Contaminated or degraded transmission fluid causing solenoid sticking or sluggish operation
20%
Wiring harness damage, chafing, or corroded connectors in the solenoid circuit
15%
Defective TCM unable to properly control solenoid output
10%
Internal transmission mechanical failure affecting hydraulic pressure to the solenoid valve body
Diagnostic Steps
1
Check transmission fluid level and condition; dark, burnt-smelling, or debris-laden fluid indicates internal wear and can cause solenoid performance issues.
2
Access the transmission connector and inspect all wiring and pins to shift solenoid "D" for corrosion, bent pins, or damaged insulation.
3
Use a multimeter to measure the resistance of shift solenoid "D"; compare to manufacturer specifications (typically 10–25 ohms). Out-of-range readings confirm a faulty solenoid.
4
Command the solenoid on and off using the scan tool's bidirectional controls while monitoring current draw to verify proper actuation.
5
Monitor transmission fluid pressure at the solenoid "D" circuit using a pressure gauge to verify the valve body is routing hydraulic pressure correctly.
6
If all electrical tests pass, inspect the valve body for stuck valves or debris blocking the solenoid's hydraulic channel.

The most common cause of P0981 (Shift Solenoid "D" Control Circuit Range/Performance) is: Faulty shift solenoid "D" with internal mechanical or electrical degradation
Typical repair costs for P0981 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Erratic or unpredictable shifting can cause loss of power or unexpected gear changes during acceleration or highway driving, posing a moderate safety risk. Limp mode reduces available power which can be hazardous when merging or passing.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0981 to identify the root cause.
