P0868 on Chevrolet
Transmission Fluid Pressure Low
P0868 on Chevrolet vehicles indicates transmission fluid pressure low. Au7o has documented this code across 3 Chevrolet models — most commonly on Spark, Trailblazer, Traverse. This code indicates the transmission's internal fluid pressure is reading lower than the computer expects for current operating conditions. The transmission control module uses a pressure sensor to monitor line pressure, which is what applies the clutches and bands that engage gears. When that pressure stays below the target threshold, P0868 sets. Low line pressure can cause slipping, harsh or delayed shifts, and in severe cases internal clutch damage, so it should be addressed promptly. Typical repair costs on Chevrolet range from $200 to $4,500, depending on the specific model and root cause.
Common Causes of P0868
- •Low transmission fluid level
- •Worn or stuck-open pressure control solenoid
- •Internal leak (worn seals, gaskets, or valve body)
- •Faulty transmission fluid pressure sensor
- •Clogged transmission filter
- •Failing transmission (oil) pump
- •Worn or leaking valve body
- •Wiring or connector fault to the pressure sensor/solenoid
P0868 on Chevrolet by Model
Chevrolet Spark(1 issue)
- CVT Transmission Shudder and Failure2016-2022
The Spark's CVT (continuously variable transmission) develops shuddering during acceleration, particularly between 20-40 mph. The transmission can eventually fail completely, leaving the vehicle unable to move. The issue is linked to belt wear and pulley degradation.
Chevrolet Trailblazer(1 issue)
- CVT Transmission Shudder and Hesitation2021-2026
The Trailblazer with the 1.2L turbo and CVT automatic develops shudder during light acceleration and hesitation from stops. Some owners report a rubber-band feel typical of CVT calibration issues.
Chevrolet Traverse(1 issue)
- Start/Stop Accumulator Missing Bolts Causing Transmission Fluid Leak / Loss of Propulsion (Recall N202313440)2018-2020
Certain 2018-2020 Traverse units (with the global front-wheel-drive 6- or 9-speed transmission) left the factory with missing or loose bolts on the start/stop transmission accumulator endcap. This can cause a transmission fluid leak that may progress to a loss of propulsion while driving, and leaking ATF near an ignition source raises fire risk. GM issued safety recall N202313440 (NHTSA 20V-668) covering this defect across multiple GM models, with the remedy beginning December 15, 2020.

What does P0868 mean on Chevrolet?▼
P0868 stands for "Transmission Fluid Pressure Low." This code indicates the transmission's internal fluid pressure is reading lower than the computer expects for current operating conditions. The transmission control module uses a pressure sensor to monitor line pressure, which is what applies the clutches and bands that engage gears. When that pressure stays below the target threshold, P0868 sets. Low line pressure can cause slipping, harsh or delayed shifts, and in severe cases internal clutch damage, so it should be addressed promptly. On Chevrolet specifically, this code is documented across 3 models.
