Transmission Pressure Control Solenoid 'D' Electrical Malfunction
Code P2716 indicates an electrical fault in the pressure control solenoid 'D' circuit, which regulates hydraulic pressure for clutch or band application in the automatic transmission. The Powertrain Control Module (PCM) detects an open, short, or excessive resistance in the solenoid circuit, often due to wiring issues, connector corrosion, or a failed solenoid. This can lead to harsh shifting, slipping, or transmission overheating.
01. Most Common Causes
- Faulty pressure control solenoid 'D'
- Open or shorted wiring in solenoid circuit
- Corroded or damaged connector
- Low transmission fluid level or contamination
- Internal transmission failure (less common)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission slipping or delayed engagement
- Reduced fuel economy
- Transmission stuck in limp mode or a single gear
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top off or replace if necessary.
Step 3: Visually check wiring and connectors for damage, corrosion, or loose pins.
Step 4: Test solenoid resistance with a multimeter (typically 4-6 ohms); compare to specs.
Step 5: Perform a voltage drop test on the solenoid circuit to identify opens or shorts.
Step 6: If wiring and solenoid test OK, check PCM for faults or reprogram if needed.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the transmission may shift harshly or slip, potentially causing internal damage. Limp mode may limit speed to prevent further issues.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, including diagnostic time and parts. Replacing a solenoid can cost $150-$300 for parts and labor, while wiring repairs may be less.
