How severe is this DTC?
The severity of this code typically starts as moderate but can quickly escalate to a more severe level if not addressed promptly. In situations causing transmission clunking during gear engagement, permanent internal damage may occur, making the issue serious.
What are some symptoms of the code?
Symptoms of a P282D trouble code may include:
- Increased fuel consumption
- Check engine light illuminated
- Transmission overheating
- Transmission slipping during gear shifts
- Harsh transmission shifting (gear clunking)
- Symptoms resembling misfires
- Transmission enters limp mode by PCM
What are some common causes of the code?
Causes of this P282D transmission code may include:
- Faulty pressure control solenoid
- Contaminated transmission fluid
- Restricted transmission filter
- Defective transmission pump
- Faulty transmission valve body
- Blocked hydraulic passages
- Corroded or damaged connector
- Faulty or damaged wiring
- Defective PCM
What are the troubleshooting steps for P282D?
Before beginning the troubleshooting process for any malfunction, you should research technical service bulletins (TSBs) for the specific vehicle by year, model, and transmission. In some situations, this can save significant time in the long run by pointing you in the right direction.
Fluid and wiring inspections
The first step is to check the fluid level and examine the fluid condition for contamination. Before changing the fluid, you should (if possible) check vehicle records to verify when the filter and fluid were last changed.
A detailed visual inspection to check wiring condition for obvious defects follows. Check connectors and connections for security, corrosion, and damaged pins. This should include all wiring and connectors for transmission pressure control solenoids, transmission pump, and PCM. Depending on the specific configuration, the transmission pump may be electrically or mechanically driven.
Advanced steps
Advanced steps always become very vehicle-specific and require appropriate advanced equipment to operate accurately. These procedures require a digital multimeter and vehicle-specific technical references. You should always obtain troubleshooting data specific to your vehicle before proceeding with advanced steps. Voltage requirements vary depending on the specific vehicle model. Fluid pressure requirements may also vary based on transmission design and configuration.
Continuity checks
Unless otherwise indicated in technical data, normal readings for wiring and connections should be 0 ohms resistance. Continuity checks should always be performed with power disconnected from the circuit to avoid short-circuiting and causing additional damage. Resistance or lack of continuity indicates faulty wiring that is open or shorted and must be repaired or replaced.
What are the common repairs for this code?
- Fluid and filter replacement
- Replace faulty pressure control solenoid
- Repair or replace defective transmission pump
- Repair or replace faulty transmission valve body
- Transmission flush to clean passages
- Clean connector corrosion
- Repair or replace faulty wiring
- Flash or replace defective PCM
Possible misdiagnosis may include:
- Engine misfire issue
- Transmission pump malfunction
- Internal transmission problem
- Transmission issue
