What P0867 means
P0867 to P0869 cover the system or line pressure of the gearbox as a whole: a pressure sensor measures it and the control module compares it with the pressure it commands. Faults of the sensor circuit itself have their own codes (Chrysler 68RFE P0932 ff), the single switches A to H have theirs (P0840 ff). Thresholds are not published; the codes are documented in bulletins for the Ram 68RFE and for the Tremec dual clutch of Corvette C8 and Maserati MC20. P0867 is the general pressure fault. GM's Corvette bulletin reads it as 'no system pressure': the pump delivers nothing or the fluid is almost gone, so valve cleaning is pointless and the gearbox needs a mechanical check. The car may lose drive completely.
P0867 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 12 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0867
- Transmission warning lamp or MIL on
- Weak or no drive
- Limp mode, car may be stranded
Common causes of P0867
- Most likelyFluid level extremely low or leak
- PossibleFluid pump or its drive faulty
- PossiblePressure regulator or relief valve sticking
- Less likelySystem pressure sensor faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0867 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. |
| 67 | The exact fault in that area. |
What to do next
- Note P0867 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 P0867
What does P0867 mean?
P0867 means "Transmission Fluid Pressure". P0867 to P0869 cover the system or line pressure of the gearbox as a whole: a pressure sensor measures it and the control module compares it with the pressure it commands. It is a generic code, so it means the same on every make.
Is it safe to drive with P0867?
Drive gently and only to a workshop. With P0867 the car can go into limp mode (reduced power) to protect itself.
Will P0867 fail an emissions test?
Yes, it can. P0867 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 P0867 to fix?
Difficulty: hard. A typical repair takes 1 to 12 hours of work. This is a job for a workshop.
Will P0867 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
