P2719: Pressure Control Solenoid 'D' Control Circuit Range/Performance
The P2719 code indicates that the Transmission Control Module (TCM) has detected a malfunction in the pressure control solenoid 'D' circuit. This solenoid regulates hydraulic pressure to apply or release clutches and bands for gear shifting. The code is set when the solenoid's actual performance deviates from the expected range, often due to electrical issues, internal transmission problems, or low fluid levels.
01. Most Common Causes
- Faulty pressure control solenoid 'D'
- Wiring or connector issues in the solenoid circuit
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
- Faulty TCM
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifting
- Transmission slipping
- Vehicle stuck in limp mode or a single gear
- Decreased fuel economy
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 connections.
Step 4: Test solenoid resistance and power/ground circuits with a multimeter.
Step 5: Perform a pressure test to verify solenoid operation and transmission hydraulic function.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause further transmission damage. Limp mode may limit speed and gear selection.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, depending on whether the solenoid is replaced individually or as part of a larger transmission service.
