Shift Solenoid D Control Circuit High
What it means
P0983 means the transmission control module sees higher-than-expected voltage in the control circuit for shift solenoid D, one of the valves that engages a gear. It usually points to an open or high-resistance wire, a failed solenoid, or a bad connection, and commonly shows up as shifting problems, harsh engagement, or a limp-mode fixed gear.
Can I keep driving? Usually driveable but with poor shift quality or a limp-mode fixed gear — repair it soon to avoid clutch wear.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the shift solenoid D wiring and connector for opens or corrosion.
- Measure the solenoid resistance against spec; replace shift solenoid D if out of range.
- Clean and re-seat the transmission connector, checking for damaged pins.
- If wiring and solenoid test good, have the TCM diagnosed last.
