Shift Solenoid E Stuck On
The P0772 code indicates that the Powertrain Control Module (PCM) has detected a malfunction in the shift solenoid 'E' circuit, specifically that the solenoid is stuck in the 'on' position. This solenoid is responsible for controlling hydraulic pressure to engage specific gears in the automatic transmission. When stuck on, it can cause improper gear engagement, harsh shifts, or transmission slippage. The issue may be electrical (wiring, connector, solenoid resistance) or mechanical (blocked fluid passages, debris).
01. Most Common Causes
- Faulty shift solenoid E
- Damaged wiring or connector to solenoid E
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifts
- Transmission stuck in 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 up or replace if necessary.
Step 3: Visually check wiring and connectors to solenoid E for damage or corrosion.
Step 4: Test solenoid E resistance with a multimeter (typically 20-30 ohms); replace if out of spec.
Step 5: If solenoid and wiring are OK, perform a transmission pressure test to confirm internal issues.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with a stuck solenoid can cause further transmission damage, erratic shifting, or complete transmission failure. Have it diagnosed and repaired promptly.
How much does it cost to fix?▼
Repair costs vary. Replacing a solenoid typically costs $150-$400 including parts and labor. If internal transmission damage is found, costs can exceed $1,500.
