P0983
Shift Solenoid D Control Circuit High
Transmission
Generic OBD-II
Medium
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.
Medium
Can I keep driving? Usually driveable but with poor shift quality or a limp-mode fixed gear — repair it soon to avoid clutch wear.
Common symptoms
What you'll notice
- Check-engine light on
- Difficulty shifting gears
- Harsh shifting or clunking during shifts
- Reduced acceleration or transmission in limp mode
Common causes
Most likely first
- Open or high-resistance wiring in the shift solenoid D circuitLikely
- Failed shift solenoid DCommon
- Loose or corroded electrical connectorCommon
- Faulty transmission control module (TCM)Less often
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.
FAQ
Quick answers
Is it safe to drive with P0983?+
Short-term yes, but the transmission may shift harshly or be stuck in a protective gear. Fix it before prolonged slipping or harsh engagement damages the clutches.
Can I just clear P0983?+
It will return until the electrical fault is repaired — clearing alone does not fix the circuit.
