Transmission

P0982 — Shift Solenoid D Control Circuit Range/Performance

Severity: medium Drive with care, to a shop

What P0982 means

The transmission control unit energizes shift solenoid D to direct hydraulic pressure to a clutch or valve so the transmission can change gears. P0982 sets when the circuit's electrical behavior or the transmission's response to the command does not match what is expected. Which gear is affected depends on how the manufacturer assigns solenoid D.

Symptoms

  • Check Engine or transmission warning light on
  • Slipping in a specific gear
  • Harsh, flared or delayed shifts
  • Transmission stuck in one gear (limp mode)
  • Jerking during gear changes
  • Worse fuel economy

Possible causes

  1. Sticking or worn shift solenoid D
  2. Contaminated or degraded transmission fluid
  3. Debris in the valve body
  4. Damaged wiring, corroded or loose connector
  5. Short to ground in the solenoid circuit
  6. Failed transmission control module (TCM/PCM)

How to diagnose

  1. Scan all codes and freeze-frame data and look for other transmission codes
  2. Check transmission fluid level and condition: color, smell, metal particles
  3. Inspect the transmission connector and harness for damage, moisture and corrosion
  4. Measure solenoid D resistance and compare it to the factory specification
  5. Test the circuit for shorts to ground and open circuits back to the control module
  6. Command the solenoid with a scan tool and check line pressure
  7. Drop the pan and inspect the magnet and filter for debris
  8. If solenoid and wiring are good, evaluate the valve body and control module

Common fixes

  • Replace transmission fluid and filter
  • Replace the faulty shift solenoid D
  • Clean or rebuild the valve body
  • Repair the wiring or connector
  • Reprogram or replace the control module once it is confirmed faulty

Questions and answers

What does P0982 mean?

The transmission control unit sees shift solenoid D behaving differently from what it commanded. The cause may be electrical, such as wiring or the solenoid itself, or mechanical, such as a stuck valve or debris in the valve body.

Can I drive with P0982?

Only briefly and carefully until it is diagnosed. If the transmission slips or goes into limp mode, limit driving, since continued use can badly damage the clutches.

Will changing the fluid fix P0982?

Sometimes, if dirty fluid or a slightly sticky solenoid is the cause. If the pan contains a lot of metal debris or the solenoid has failed, a fluid change alone won't solve it.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
