What Does P2813 Mean?
The TCM has detected that pressure control solenoid 'G' is operating outside its expected range or not performing correctly. The solenoid is functioning but not achieving the desired pressure control parameters.
Common Causes
35%
Worn or sticking pressure control solenoid 'G' with degraded performance
25%
Low transmission fluid level or wrong fluid type affecting pressure regulation
20%
Restricted transmission filter or clogged fluid passages reducing flow to solenoid
12%
High resistance in solenoid circuit due to corrosion or damaged wiring
8%
Internal transmission wear causing pressure loss or leakage
Diagnostic Steps
1
Step 1: Check transmission fluid level, condition, and verify correct fluid specification is being used
2
Step 2: Monitor live data for commanded vs actual pressure readings from pressure sensors
3
Step 3: Measure solenoid resistance and compare to specifications; check for high resistance in circuit
4
Step 4: Perform transmission pressure test at various operating conditions to identify pressure deviations
5
Step 5: Remove valve body and inspect solenoid 'G', filter, and fluid passages for debris or mechanical wear
Estimated Repair Cost
$300 - $1,500
Parts + labor, varies by vehicle and location
The TCM has detected that pressure control solenoid 'G' is operating outside its expected range or not performing correctly. The solenoid is functioning but not achieving the desired pressure control parameters.
The most common cause of P2813 (Pressure Control Solenoid "G" Control Circuit Range/Performance) is: Worn or sticking pressure control solenoid 'G' with degraded performance
Typical repair costs for P2813 range from $300 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may exhibit poor shift quality, slipping, or harsh engagements. Extended operation can lead to clutch or band damage from improper line pressure.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2813 to identify the root cause.
