What Does P0969 Mean?
The TCM has determined that Pressure Control Solenoid C (PCS-C) is not performing within its expected operating range. The solenoid responds to commands but its output does not match the target — either the actual pressure deviates from commanded pressure or the current draw is abnormal. This results in degraded shift quality or torque converter clutch operation depending on the transmission design.
Common Causes
35%
PCS-C sticking or responding sluggishly due to contamination or mechanical wear
25%
Contaminated or deteriorated transmission fluid impeding solenoid movement
20%
Elevated resistance in PCS-C wiring reducing actual current below commanded levels
15%
Worn valve body bore where PCS-C seats, causing pressure leakage
5%
TCM adaptive values or calibration out of range
Diagnostic Steps
1
Inspect transmission fluid for contamination, discoloration, or metallic debris. Fluid condition directly affects solenoid performance.
2
Using enhanced scan tool data, compare PCS-C commanded duty cycle vs. actual pressure or current. Document the deviation magnitude and conditions.
3
Measure PCS-C resistance at the transmission connector and verify it is within specification. Also measure total circuit resistance including the external harness to find any added resistance.
4
If possible, remove PCS-C from the valve body and inspect for contamination, varnish, or physical damage. Check the solenoid inlet screen for blockage.
5
Service the transmission fluid and filter, reset TCM adaptive values, and perform a road test to evaluate whether PCS-C performance returns to normal.

The most common cause of P0969 (Pressure Control Solenoid "C" Control Circuit Range/Performance) is: PCS-C sticking or responding sluggishly due to contamination or mechanical wear
Typical repair costs for P0969 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle remains drivable but with degraded shift or lockup quality. Prolonged operation with out-of-range pressures can accelerate clutch and band wear. Address promptly to prevent escalation into a more costly internal transmission repair.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0969 to identify the root cause.
