What Does P0867 Mean?
The transmission control module (TCM) has detected that the transmission fluid pressure is outside of the expected range. This code is a general indicator that the hydraulic pressure within the transmission is not meeting specifications, which can affect shift quality and overall transmission operation. It may be accompanied by harsh shifts, slipping, or delayed engagement.
Common Causes
30%
Low transmission fluid level or degraded fluid
25%
Faulty transmission fluid pressure sensor
20%
Worn or clogged transmission fluid filter
15%
Failing transmission fluid pump
10%
Internal transmission valve body malfunction
Diagnostic Steps
1
Check transmission fluid level and condition — fluid should be red/pink, not brown or burnt-smelling.
2
Monitor live data for transmission fluid pressure PID and compare to manufacturer specifications at various RPMs.
3
Inspect wiring and connectors to the transmission fluid pressure sensor for damage, corrosion, or loose pins.
4
Perform a transmission fluid pressure test using a mechanical gauge to verify sensor accuracy.
5
Inspect the transmission pan for debris or metal shavings that could indicate internal wear.
Estimated Repair Cost

The most common cause of P0867 (Transmission Fluid Pressure) is: Low transmission fluid level or degraded fluid
Typical repair costs for P0867 range from $100 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Drive cautiously to a shop. Abnormal transmission pressure can cause erratic shifting. Avoid heavy towing or aggressive driving until the issue is diagnosed.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0867 to identify the root cause.
