P0982 — Shift Solenoid "D" Control Circuit Low

How much does it cost to fix P0982?

Transmission fluid service — $150–$350; Valve body repair or replacement — $700–$1,500; Transmission rebuild or replacement — $2,500–$5,500; Replace a shift solenoid — $300–$800. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does OBD2 code P0982 mean?

Shift Solenoid "D" Control Circuit Low (P0982): a powertrain (engine/transmission) fault affecting the automatic transmission control. Short, gentle driving to a shop is usually possible. Most often caused by valve body wear, internal mechanical wear (clutches, torque converter), low or degraded transmission fluid.

How do I diagnose P0982 myself?

Start with a scan: confirm P0982, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the shift solenoid "D" control, and verify the suspect component against live data before buying parts.

What is the most common cause of P0982?

The most common causes are: valve body wear, internal mechanical wear (clutches, torque converter), low or degraded transmission fluid.

What are the symptoms of P0982?

Drivers most often notice: Check Engine or transmission warning light on, transmission stuck in one gear (limp mode), slipping between gears, shuddering at highway speed.

When your vehicle's engine control unit stores trouble code P0982, it's reporting a specific electrical problem inside the automatic transmission: the shift solenoid "D" control circuit is reading abnormally low voltage. In practical terms, this means the signal keeping that solenoid energized has dropped close to ground potential — essentially zero volts where several volts should be. The PCM logs P0982 only after running multiple verification checks during a drive cycle, so a single momentary glitch typically won't trigger it.

The transmission control module depends on precise electrical signals to manage gear shifts smoothly. Shift solenoid "D" is one of several electro-hydraulic valves inside the valve body that direct transmission fluid pressure to engage the correct gear. When P0982 appears, the module detects that the control circuit feeding this solenoid isn't maintaining proper voltage. The culprit is usually a short circuit pulling the signal to ground — either in the wiring harness itself or within the solenoid's internal components. Occasionally, a broken feed wire or a corroded connector can starve the circuit entirely, producing the same low-voltage reading the control unit recognizes as P0982.

Because the PCM stores freeze frame data alongside P0982, the exact operating conditions when the fault first appeared — engine RPM, load, vehicle speed, and transmission fluid temperature — remain captured for reference during diagnosis.

Common Symptoms of P0982

• The check engine light or transmission warning indicator illuminates on the dashboard
• Transmission defaults to limp mode, locking the vehicle in a single gear
• Noticeable gear slippage where the transmission fails to hold the selected gear
• Vibration or shuddering sensation, particularly at highway speeds
• Complete loss of forward or reverse movement in more severe cases
• Shifting feels harsh or is noticeably delayed when accelerating

What Causes P0982?

The most frequent root causes are electrical in nature, though mechanical wear inside the transmission can also produce this code:

• Loss of supply voltage reaching the shift solenoid "D" control circuit
• Signal wire shorted to ground from damaged, chafed, or melted insulation
• Failed shift solenoid "D" internal windings dragging the circuit voltage down
• Worn valve body passages or solenoid bore scoring
• Damaged connectors or broken wires within the transmission harness
• Internal transmission wear affecting hydraulic circuits (clutch plates, torque converter)
• Coexisting failure of another shift solenoid or pressure control solenoid
• Faulty transmission input/output speed sensor sending misleading data

How to Diagnose P0982

Effective diagnosis separates the true culprit from a cascade of symptoms. Follow these steps in order:

1. Connect a compatible OBD2 scanner, confirm P0982 is actively stored, and record all freeze frame data before clearing anything. This snapshot reveals exactly what the engine and transmission were doing when the fault occurred.
2. Pull all stored and pending codes from the transmission control module. Related codes often point toward the actual failure — a failing speed sensor might trigger P0982 as a secondary fault. Also check for any manufacturer technical service bulletins covering P0982 on your specific make and model.
3. Perform a thorough visual inspection of the transmission wiring harness and connectors. Look for rubbed-through insulation, melted wire coatings, corrosion buildup, or connectors that aren't fully seated. The harness near the valve body is especially vulnerable to heat and movement damage.
4. Test for supply voltage at the shift solenoid "D" connector with the key on and engine off. Then measure resistance from the signal terminal to ground — a reading near zero ohms confirms a direct short to ground somewhere in the harness.
5. Inspect transmission fluid level and condition. Burnt-smelling, dark brown or black fluid indicates clutches are slipping or the torque converter is failing, which can produce electrical symptoms as well.
6. Use a transmission-capable scanner to monitor live solenoid operation, input and output shaft speeds, and applied line pressure while wiggling the harness. This can reveal intermittent shorts that don't show up with static multimeter tests.
7. Clear P0982 and complete a test drive that recreates the freeze frame conditions (same speed, load, and temperature range). If the code returns, the fault is confirmed and not a one-time electrical glitch.

Repair Options and Costs

Resolution depends entirely on which component triggered P0982 in the first place. The following price ranges cover parts and labor at independent shops in the United States:

• Transmission fluid and filter service — $150–$350. A complete drain and fill with fresh fluid and filter is often the first and cheapest remedy, especially if contamination contributed to solenoid failure.
• Shift solenoid replacement — $300–$800. If testing confirms the solenoid itself is failed, replacing just that unit is far more economical than more extensive work.
• Valve body repair or replacement — $700–$1,500. When the problem lies within the valve body's hydraulic passages or multiple solenoids, removing and rebuilding or replacing the entire valve body may be necessary.
• Transmission rebuild or replacement — $2,500–$5,500. Severe internal wear — damaged clutches, a failed torque converter, or major valve body damage — pushes costs into this range. Used or rebuilt units typically cost less than brand-new transmissions.

How Much Does Fixing P0982 Cost Overall?

The total bill for addressing P0982 falls anywhere between $150 and $5,500, depending on which part actually failed. In most cases, the problem is either low transmission fluid, a single failed solenoid, or wiring damage — all of which sit on the lower end of the cost spectrum. A transmission teardown or full replacement is comparatively rare as an initial cause of this code. Getting an accurate diagnosis before purchasing any parts is the single most effective way to avoid paying for work you don't need.

Can You Drive With P0982?

Caution is warranted. If the transmission still shifts and the vehicle moves without slipping or shuddering, short trips on lower-speed roads are acceptable in the near term. However, avoid sustained highway driving when P0982 is active. Limp mode operation puts additional stress on remaining transmission components, and every mile driven in degraded conditions can expand the scope of damage — and the final repair bill. Get the code diagnosed and repaired before it escalates.
