P0983 – Shift Solenoid D Control Circuit High: Symptoms, Causes, Diagnosis & Repair Cost (2026 Guide)

P0983

Last updated:

Overview

The control module stored P0983 because it detected a problem with: Shift Solenoid D Control Circuit High.

P0983 relates to Shift Solenoid D Control Circuit High. Use a quality scan tool, follow wiring diagrams for your vehicle, and confirm tests before replacing expensive parts.

What does the P0983 code mean?

When P0983 is set, the vehicle’s diagnostics detected an issue described as: Shift Solenoid D Control Circuit High. In practice, the ECM/PCM (and related modules) compare sensor inputs, commanded outputs, and self-tests for that subsystem. The exact repair depends on whether the fault is wiring-related, component-related, or a rationality/performance issue for this circuit or system.

Common symptoms of P0983

  • Poor acceleration
  • Harsh or delayed shifting
  • Limp mode or limited gears
  • Slipping or flaring
  • Check engine light
  • Transmission warning indicator

Possible causes

  • Fault affecting Shift Solenoid D Control Circuit High (wiring, connector, or component)
  • Faulty sensor output stuck high
  • Open ground/reference path
  • Short-to-power or stuck-high signal condition
  • Control module or software calibration issue (less common—verify tests first)
  • Past repairs or aftermarket parts causing out-of-spec operation

How to diagnose P0983

  1. Scan for P0983 and review freeze frame / pending codes for related faults
  2. Inspect connectors and wiring related to: Shift Solenoid D Control Circuit High
  3. Compare live data and commanded vs actual values for the affected system (per service information)
  4. Perform circuit tests appropriate to the fault type (continuity, voltage, resistance) before replacing parts
  5. Confirm power and ground integrity at the relevant module or sensor
  6. After repair, clear DTCs and verify under the conditions that originally set P0983

Tip: Use a scan tool that shows live data and freeze frame for the conditions when the code set.

Severity of code P0983

Moderate: Have this code diagnosed soon; ignoring it can lead to worse fuel economy, repeat failures, or secondary damage.

Can you drive with P0983?

Short trips may be okay if the vehicle feels normal, but have it diagnosed—especially if performance, safety warnings, or overheating are present.

Avoid heavy acceleration, towing, or long highway drives until the cause of P0983 is confirmed and repaired.

How to fix it (step-by-step)

  1. Start with visual inspection and connector cleaning/tightening where needed
  2. Confirm failure mode with testing—avoid swapping parts without evidence
  3. Repair wiring or replace the failed component per manufacturer procedure
  4. Clear faults, run relearns if required, and road test to confirm

Repair & fix options

  • Replace component if output remains invalid
  • Restore proper reference/ground
  • Repair short-to-voltage sources
  • Clear codes and verify repair with a drive cycle and readiness where applicable
  • Reinspect related monitors if the code returns after repair

Typical repair cost

$150 – $4,500+ depending on cause

Estimated cost breakdown for P0983
Repair type Typical range
Fluid And Filter Change $150 – $450
Solenoid Replacement $350 – $1,800
Speed Sensor Or Internal $900 – $2,800
Transmission Rebuild Or Replace $1,500 – $4,500+

How to help prevent P0983 in the future

  • Fix new codes early before secondary damage or catalyst stress
  • Keep connectors clean and secure; address rodent or water intrusion in harnesses
  • Use the correct fluids/parts for your vehicle and service intervals
  • Avoid ignoring pending codes after battery work or repairs

When to see a mechanic

Schedule diagnosis if the check engine light is on, drivability is worse, or you notice new noises, smells, or warning lamps. For safety-related (SRS/ABS) or overheating symptoms, prioritize a qualified shop immediately.

Common mistakes when diagnosing P0983

  • Replacing sensors/modules without verifying wiring and reference voltages
  • Ignoring related codes that identify the real root cause
  • Clearing codes without a verification drive cycle

Common vehicles & notes for P0983

  • Ram / Jeep models (common examples—verify for your vehicle)
  • Subaru / GMC applications vary by engine and model year
  • Many other makes—this is a standardized OBD-II definition: Shift Solenoid D Control Circuit High

P0983 is reported across many platforms including Ram, Jeep, Subaru, GMC. Always use VIN-specific service information for testing limits and calibration steps.

Frequently asked questions

What does P0983 mean?

P0983 indicates a fault involving Shift Solenoid D Control Circuit High, based on what the control module detected during self-tests or live monitoring.

Is it safe to drive with P0983?

If the vehicle runs normally and no warning lights are flashing, short trips may be reasonable—but avoid ignoring symptoms like misfire, overheating, ABS/SRS warnings, or major loss of power.

How much does it cost to fix P0983?

Typical repairs often fall in the ranges shown on this page, but final cost depends on labor rate, parts quality, and whether the issue is wiring vs. a major component.

What is the most common cause of P0983?

Most shops start with wiring/connectors and the directly monitored component for “Shift Solenoid D Control Circuit High,” then expand testing if the fault returns.

Will P0983 clear itself?

It may become intermittent, but if the underlying fault remains, the code will usually return—especially after a drive cycle.

Can a weak battery cause P0983?

Low system voltage can cause odd sensor/module behavior, but you should still validate the actual DTC and perform normal circuit/component tests.
