Transmission Pressure Control Solenoid Intermittent
The P2717 code indicates an intermittent fault in the transmission pressure control solenoid circuit. This solenoid regulates hydraulic pressure to the clutches and bands for smooth shifting. An intermittent signal suggests a loose connection, wiring issue, or failing solenoid that works sporadically, leading to erratic transmission behavior.
01. Most Common Causes
- Faulty pressure control solenoid
- Wiring or connector damage (corrosion, loose pins, broken wires)
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light on
- Harsh or delayed shifting
- Transmission slipping or overheating
- Reduced 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.
Step 3: Visually check wiring and connectors to the solenoid for damage or corrosion.
Step 4: Test solenoid resistance and power/ground circuits with a multimeter.
Step 5: Perform a transmission pressure test to verify solenoid operation.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
Not recommended. Driving with an intermittent solenoid can cause erratic shifting, transmission damage, or sudden loss of drive. Have it diagnosed promptly.
How much does it cost to fix?▼
Repair costs range from $150 to $400 for solenoid replacement, plus diagnostic fees. If internal damage is found, costs can exceed $1,500.
