Transmission Friction Element Stuck Off
The P07AE code indicates that the transmission control module (TCM) has detected a malfunction in one of the transmission's friction elements (such as a clutch or band). This element is not engaging properly or is stuck in the off position, which can cause shifting issues, slipping, or loss of drive. The problem may be due to hydraulic circuit failures, solenoid issues, or internal mechanical damage.
01. Most Common Causes
- Faulty transmission solenoid
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
- Wiring or connector issues in the transmission circuit
02. Symptoms You Will Notice
- Harsh or delayed shifting
- Transmission slipping or jerking
- Check Engine Light illuminated
- Vehicle may go into limp mode
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and check freeze frame data.
Step 2: Inspect transmission fluid level and condition; top off or replace if necessary.
Step 3: Test transmission solenoids and wiring harness for continuity and resistance.
Step 4: Perform a transmission pressure test to identify hydraulic circuit issues.
Step 5: If no external issues found, internal transmission inspection may be required.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code as it can cause further transmission damage and unsafe driving conditions.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150, but repairs can range from a few hundred dollars for solenoid replacement to several thousand for a transmission rebuild or replacement.
