What Does P2829 Mean?
The transmission control module has determined that Pressure Control Solenoid K is stuck in the off position or not responding to commands. This prevents proper transmission pressure regulation and can affect shift quality and gear engagement.
Common Causes
35%
Mechanical failure or sticking of pressure control solenoid K
25%
Debris or sludge in valve body blocking solenoid operation
20%
Solenoid screen or filter clogged with contaminants
15%
Valve body wear or damage preventing proper pressure control
5%
Wiring issue causing insufficient voltage to solenoid K
Diagnostic Steps
1
Step 1: Check transmission fluid condition for debris, metal particles, or varnish buildup
2
Step 2: Command solenoid K on/off using scan tool bidirectional controls and monitor response
3
Step 3: Measure solenoid K current draw during operation to verify mechanical freedom
4
Step 4: Remove transmission pan and inspect solenoid K and valve body for debris or damage
5
Step 5: Test removed solenoid K with direct power application and listen/feel for proper actuation
Estimated Repair Cost
$300 - $1,500
Parts + labor, varies by vehicle and location
The transmission control module has determined that Pressure Control Solenoid K is stuck in the off position or not responding to commands. This prevents proper transmission pressure regulation and can affect shift quality and gear engagement.
The most common cause of P2829 (Pressure Control Solenoid "K" Performance/Stuck Off) is: Mechanical failure or sticking of pressure control solenoid K
Typical repair costs for P2829 range from $300 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Can cause loss of specific gears, harsh shifting, or transmission slipping. May result in unexpected vehicle behavior during acceleration or deceleration.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2829 to identify the root cause.
