P0868 on Mitsubishi by model: symptoms, diagnosis and fix
The Jatco CVT in the Outlander is prone to premature failure, particularly under heavy loads and in hot climates. The CVT belt and pulleys wear prematurely, leading to slipping, shuddering, and eventual complete transmission failure, often between 60,000 and 100,000 miles.
Common Symptoms
- Transmission shuddering during acceleration
- Loss of power at highway speeds
- Whining noise increasing with speed
- CVT overheating warning
How to Fix
Change CVT fluid every 30,000 miles using Mitsubishi DiaQueen CVTF-J4. Avoid aggressive driving and towing near maximum capacity. If the CVT fails, replacement with a remanufactured unit is more cost-effective than rebuild.
Non-Evolution Lancer models with the CVT experience premature transmission failure, with the CVT belt and pulleys wearing out between 80,000 and 120,000 miles. The transmission develops slipping, shuddering, and eventually complete failure.
Common Symptoms
- Transmission slipping
- Shudder during acceleration
- Whining noise from transmission
- Loss of drive at highway speeds
How to Fix
Regular CVT fluid changes every 30,000 miles can extend transmission life. When the CVT fails, a remanufactured unit from a reputable rebuilder is more cost-effective than a new Mitsubishi unit.

Frequently asked questions
What does P0868 mean on a Mitsubishi?
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 Mitsubishi it is documented across 2 models: Outlander, Lancer.
What are the most common causes of P0868?
The most common causes of P0868 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0868 on a Mitsubishi?
Published repair estimates on Mitsubishi range from $2,500 to $7,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
