P0867 on Chevrolet
Transmission Fluid Pressure
P0867 on Chevrolet vehicles indicates transmission fluid pressure. Au7o has documented this code across 1 Chevrolet model — most commonly on Corvette. This generic powertrain code indicates the transmission control module detected that the measured transmission fluid (line) pressure is outside the expected range. Proper hydraulic pressure is essential for applying clutches and bands and for smooth, correctly timed shifts, so an out-of-range reading can cause shifting problems. Causes often trace to fluid condition or level, internal hydraulic issues, or a faulty pressure sensor. Typical repair costs on Chevrolet range from $350 to $900, depending on the specific model and root cause.
Common Causes of P0867
- •Low or dirty transmission fluid
- •Transmission fluid leak
- •Faulty transmission fluid pressure sensor
- •Damaged wiring or connector to the sensor
- •Worn valve body or stuck pressure control solenoid
- •Clogged transmission filter
- •Internal transmission/pump wear

- E-Ray DCT Auxiliary Pump Cavitation - Service Transmission Message and DTCs P1955/P08672024-2026
On the E-Ray only, the 8-speed dual-clutch transmission carries an auxiliary fluid pump so the gearbox stays pressurized while the car is moving on electric power alone in Stealth or Shuttle mode. GM published Bulletin #25-NA-278 for 2024-2026 Corvette E-Ray models that display a Service Transmission message in the Driver Information Center along with an illuminated Check Engine MIL, with DTC P1955 (Transmission Fluid Pressure Relief Valve Performance) and/or P0867 (Transmission Fluid Pressure Performance) stored in the TCM. GM identifies the cause as auxiliary pump cavitation traced to the transmission pan fluid filter. This condition is specific to the hybrid E-Ray driveline and does not apply to the Stingray, Z06 or ZR1, which have no electric-only drive mode and no auxiliary pump duty cycle of this kind.
