Gate Select Actuator Circuit High
The P0913 code indicates that the transmission control module (TCM) has detected a high voltage condition in the gate select actuator circuit. This actuator is responsible for moving the shift mechanism to select the appropriate gate (e.g., Park, Reverse, Neutral, Drive) in automated manual transmissions (AMT) or dual-clutch transmissions (DCT). A high voltage reading suggests a short to power, a faulty actuator, or a wiring issue, which can prevent proper gear selection.
01. Most Common Causes
- Short to power in the gate select actuator circuit
- Faulty gate select actuator
- Damaged wiring or connector
- Faulty transmission control module (TCM)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Transmission stuck in one gear or fails to shift
- No start condition (if park/neutral safety switch affected)
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Visually inspect the gate select actuator wiring and connector for damage, corrosion, or shorts.
Step 3: Using a multimeter, check the actuator circuit for high voltage (should be within manufacturer specs).
Step 4: Test the actuator resistance and operation per service manual; replace if out of range.
Step 5: If wiring and actuator are OK, check TCM for faults and reprogram or replace if necessary.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The transmission may fail to shift properly, leaving you stranded or causing an accident. Have the vehicle towed to a repair shop.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, depending on the cause. Replacing the actuator can cost $200-$350, while wiring repairs are usually less.
