P0868 on Infiniti by model: symptoms, diagnosis and fix
The QX55 pairs the torque-rich VC-Turbo engine with a Jatco Xtronic CVT. Owners and technicians report the classic Nissan/Infiniti CVT complaints: a rubber-band or 'revving' feel where engine RPM flares without corresponding acceleration, low-speed judder/shudder while slowing to a stop, hesitation and turbo lag off the line, and overheating under sustained load. CVTs are sensitive to the engine's low-end torque, and heat plus fluid breakdown accelerate internal wear. Judder trouble codes such as P17F0/P17F1 are associated with the family.
Common Symptoms
- Engine RPM flares without acceleration (rubber-band feel)
- Shudder/judder when slowing to a stop
- Hesitation or turbo lag from a stop
- Whining or droning noise
- Harsh or delayed engagement
- Overheating / limp mode under load
How to Fix
Start with a genuine Nissan NS-3 CVT fluid exchange and check for leaks or low fluid; heat is the primary enemy. A dealer scan for judder codes can call for a valve-body/pressure recalibration or valve-body replacement. Severe cases require a CVT rebuild or replacement. Frequent fluid checks and an auxiliary cooler help; avoid heavy towing.

The Jatco CVT in the QX60 is prone to premature failure, particularly in the 2013-2017 models. The transmission overheats during towing or sustained highway driving, leading to shuddering, slipping, and eventual complete failure.
Common Symptoms
- Transmission shuddering at highway speeds
- Loss of power during acceleration
- Whining noise from transmission
- CVT overheating warning
How to Fix
Replace CVT fluid every 30,000 miles instead of the recommended 60,000. Add an auxiliary transmission cooler for towing. Nissan extended the CVT warranty to 84 months/84,000 miles on affected models.

Frequently asked questions
What does P0868 mean on a Infiniti?
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 Infiniti it is documented across 2 models: QX55, QX60.
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 Infiniti?
Published repair estimates on Infiniti range from $200 to $8,000 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.
