Shift solenoids operate like little traffic control devices, which are used by the ECU to direct the flow of pressurized transmission fluid throughout the gearbox. This allows the clutches and gears to be moved around inside the transmission can change gears. If the ECU detects a low voltage on the shift solenoid D control circuit, it will store a P0982 DTC.
How Serious is the Code?
Although the transmission problems related to a P0982 diagnostic trouble code might not seem like a big deal at first. They will eventually become very severe, and hinder the safe operation of your vehicle.
Symptoms of a P0982 include:
- Unusually harsh
- Transmission may not shift into gear
- Low transmission fluid
- Dirty transmission fluid/filter
- Damaged wiring and/or corroded or broken connectors
- Shift solenoid malfunction
How to Diagnose the Code?
The level and condition of the transmission fluid is the first thing that should be checked when trying to diagnose a P0982 OBDII trouble code. The next thing that should be checked is the condition of the wiring and connectors along the transmission wiring harness. If no broken wires or damaged connectors are found, then the shift solenoid D itself should be tested.
What Repairs Will Fix P0982?
- Service the transmission
- Replace or repair damage wiring/connectors
- Replace shift solenoid
- P0981 – Shift Solenoid “D” Control Circuit Range/Performance
- P0983 – Shift Solenoid “D” Control Circuit High
