What P0875 means
Transmission fluid pressure switches C and D report whether a clutch circuit is pressurised. They are more widespread than A and B: GM's 6L80/6L90 and 6T40/6T70 six-speeds put switch C on the 2-6 brake and D on the 1-2-3-4 clutch, Allison uses them for its third shift valve and its reverse switch, Ram's RFE gearboxes for the clutch pressure switches in the solenoid block. Ford reports pressure faults under its solenoid codes. P0875 is the general fault of D. Allison's 2006 table uses it for the reverse pressure switch: it reports reverse while the range sensor shows P, N or a forward range for over 1 s, type A. Nissan's Kicks and Versa CVT reports the high clutch switch of the auxiliary gearbox as 'sensor/switch D'; together with P285A the control valve body is replaced.

Symptoms of P0875
- MIL or transmission warning lamp on
- Judder or reduced power (Nissan)
- Reverse indication or shifting disturbed (Allison)
Common causes of P0875
- Most likelyControl valve body with pressure switch faulty (Nissan CVT)
- PossibleReverse pressure switch stuck closed (Allison)
- PossibleRange sensor misadjusted
- Less likelyWiring or connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0875 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| 75 | The exact fault in that area. |
What to do next
- Note P0875 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0875
What does P0875 mean?
P0875 means "Transmission Fluid Pressure Sensor/Switch D Circuit". Transmission fluid pressure switches C and D report whether a clutch circuit is pressurised. It is a generic code, so it means the same on every make.
Is it safe to drive with P0875?
Drive gently and only to a workshop. With P0875 the car can go into limp mode (reduced power) to protect itself.
Will P0875 fail an emissions test?
Yes, it can. P0875 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0875 to fix?
Difficulty: hard. A typical repair takes 1.5 to 5 hours of work. This is a job for a workshop.
Will P0875 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
