P2829: Pressure Control Solenoid 'G' Performance/Stuck Off
The P2829 code indicates that the Transmission Control Module (TCM) has detected a malfunction in the pressure control solenoid 'G', which is responsible for regulating hydraulic pressure within the automatic transmission. The solenoid is commanded to a specific duty cycle, but the TCM detects that the actual pressure response is not within the expected range, or the solenoid is stuck in the off position. This can lead to improper gear engagement, harsh shifts, or transmission slippage.
01. Most Common Causes
- Faulty pressure control solenoid 'G'
- Wiring or connector issues (open, short, corrosion)
- Low or contaminated transmission fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifting
- Transmission slipping or stuck in gear
- 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; top off or replace if necessary.
Step 3: Visually check wiring and connectors to solenoid 'G' for damage or corrosion.
Step 4: Test solenoid resistance and operation using a multimeter or scan tool bidirectional control.
Step 5: If solenoid tests bad, replace it; if wiring is faulty, repair as needed.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the transmission may shift erratically or fail, potentially causing a safety hazard.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, depending on labor rates and whether the solenoid or wiring needs replacement.
