P2712: Hydraulic Power Unit Leakage
The P2712 code indicates that the Transmission Control Module (TCM) has detected a leakage in the hydraulic power unit, which is responsible for providing hydraulic pressure to the transmission's shift actuators. This leakage can result from internal seal failures, worn components, or contamination in the transmission fluid, leading to insufficient pressure for proper gear engagement.
01. Most Common Causes
- Worn or damaged seals in the hydraulic power unit
- Contaminated or low transmission fluid
- Faulty hydraulic power unit assembly
02. Symptoms You Will Notice
- Delayed or harsh shifting
- Transmission slipping or failure to engage gears
03. Step-by-Step Diagnosis
Step 1: Check transmission fluid level and condition; top off or replace if necessary.
Step 2: Perform a hydraulic pressure test to identify leakage in the power unit.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, driving with P2712 can cause transmission damage and unsafe driving conditions. Have it inspected immediately.
How much does it cost to fix?▼
Repair costs typically range from $50 to $150 for fluid service, but may be higher if the hydraulic power unit needs replacement.
