What Does P0795 Mean?
The transmission pressure control solenoid C has a general malfunction. This solenoid regulates hydraulic pressure to specific clutch packs or bands within the transmission, controlling shift quality and torque capacity. A malfunction means the TCM cannot properly control line pressure in the circuits served by this solenoid, leading to harsh shifts, slipping, or failure to engage certain gears.
Common Causes
35%
Pressure control solenoid C internal failure (stuck or shorted)
25%
Contaminated transmission fluid clogging solenoid or valve body passages
20%
Wiring or connector fault in solenoid C circuit
12%
Valve body wear or debris preventing proper pressure regulation
8%
TCM driver circuit failure for solenoid C
Diagnostic Steps
1
Monitor pressure control solenoid C duty cycle and commanded pressure vs actual line pressure (if equipped with a pressure sensor PID).
2
Check transmission fluid level and condition — dark, burnt, or debris-filled fluid is the primary cause of solenoid contamination.
3
Inspect the solenoid connector and wiring for damage, corrosion, or transmission fluid contamination.
4
Measure solenoid C resistance and compare to manufacturer specification (typically 3-8 ohms for pressure control solenoids).
5
If fluid is contaminated, a valve body service or solenoid pack replacement may be necessary.
6
Perform a transmission pressure test at the appropriate ports to verify actual pressure matches commanded values.

The most common cause of P0795 (Pressure Control Solenoid C Malfunction) is: Pressure control solenoid C internal failure (stuck or shorted)
Typical repair costs for P0795 range from $200 to $1,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle may exhibit harsh shifts, slipping between gears, or delayed engagement. Driving is possible at reduced speeds, but avoid towing or heavy loads. Continued driving with improper pressure can cause accelerated clutch pack wear and lead to costly transmission failure.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0795 to identify the root cause.
