How to diagnose and fix P0746: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Nissan Cube · 2009–2014
The Jatco CVT in the Cube is prone to premature failure, typically between 80,000-120,000 miles. Owners report shuddering during acceleration, delayed engagement from Park, and eventual complete transmission failure. Nissan extended the CVT warranty on some models to 10 years/120,000 miles, but many Cubes fall outside this coverage. The CVT belt stretches and the valve body develops issues, leading to erratic behavior before total failure.
Common Symptoms
- Shuddering or juddering during acceleration
- Delayed engagement when shifting from Park to Drive
- Whining or humming noise from transmission
- RPM surging without corresponding acceleration
- Vehicle hesitates or jerks at low speeds
How to Fix
Check if your VIN qualifies for Nissan's extended CVT warranty. If experiencing early symptoms (shuddering, slipping), have the CVT fluid changed with Nissan NS-2 fluid — this can extend life. Once failure occurs, replacement with a remanufactured CVT ($2,500-$4,000) is more cost-effective than a new unit. Avoid aggressive driving and ensure CVT fluid stays clean.

Owner tips & cautions
- TipChange CVT fluid every 30,000 miles with genuine Nissan NS-2 fluid to extend transmission life.
- WarningDo NOT flush the CVT — only drain and fill. Flushing can dislodge debris and cause immediate failure.
- TipIf the CVT fails, a remanufactured unit is typically half the cost of a dealer replacement and carries a warranty.

Nissan NV200 · 2013–2021
The NV200's Jatco CVT transmission is particularly prone to failure when used for commercial delivery work, which is the vehicle's primary purpose. The constant stop-and-go driving and heavy loads accelerate CVT belt wear and valve body degradation. Many owners report failure between 60,000-100,000 miles. Symptoms include jerking during acceleration, delayed shifting, and eventually complete loss of drive.
Common Symptoms
- Jerking or shuddering during acceleration
- Delayed engagement from Park to Drive or Reverse
- Whining noise that increases with speed
- RPM fluctuation without speed change
- Complete loss of forward or reverse drive
How to Fix
Change CVT fluid every 25,000 miles with Nissan NS-2 CVT fluid — more frequently than the recommended interval given commercial use patterns. If shuddering begins, an immediate fluid change may extend life. When replacement is needed, a remanufactured CVT ($2,500-$3,500) is more economical than a dealer unit. Consider aftermarket CVT coolers for delivery vehicles.
What you need to fix it
Only diagnosis- and fitment-reviewed repair parts are linked here.
- Genuine Nissan NS-3 CVT automatic transmission fluid 999MP-CV0NS3
NV200 MR20DE CVT; confirm VIN, quantity, fluid-temperature level procedure and current service information.

Owner tips & cautions
- TipInstall an aftermarket CVT transmission cooler if you use the NV200 for delivery work — it significantly extends CVT life.
- WarningDo not exceed the NV200's payload capacity (1,480 lbs) — overloading dramatically shortens CVT lifespan.
- TipChange CVT fluid every 25,000 miles for commercial use rather than the 60,000-mile factory interval.

Cadillac XT5 · 2023–2024
GM bulletin 20-NA-136 (May 2024) gives a diagnostic and repair strategy for 9T65 nine-speed automatics (RPO M3W/M3V) in 2021-2024 XT5 and related GM crossovers that set transmission DTCs with less than 12,000 miles on the odometer. It points technicians to PIP5974 for a clutch snap-ring pop-out that can set P0746/P0747. Depending on which solenoid-related codes reproduce on a road test and on fluid condition, the bulletin calls for replacing the solenoid body and/or control valve body, and for removing the transmission to inspect the clutches when the fluid is dark and burnt. The earlier replacement pilot program has ended.
Common Symptoms
- Check engine light with transmission DTCs (such as P0746/P0747) at low mileage
- Harsh, soft or delayed shifts or slipping
How to Fix
Have a qualified technician confirm the transmission RPO and current GM guidance before choosing a repair. Bulletin 20-NA-136 calls for recording all DTCs, checking fluid level/condition and line pressure, and a road test; its replacement pilot has ended, so it does not mandate a replacement transmission. P0747 can also occur at shutdown without an internal mechanical fault. Repair scope and warranty eligibility must be established for the diagnosed condition. Ask Cadillac to check the VIN for the separate 23V172 sun-gear recall.

Frequently asked questions
What does P0746 mean?
P0746 stands for "Pressure Control Solenoid Performance/Stuck Off." P0746 means the transmission's pressure control solenoid 'A' is performing poorly or appears stuck in the off (low pressure) position. This solenoid regulates hydraulic line pressure that applies clutches and bands to make smooth, firm shifts; the TCM detects when commanded pressure changes aren't producing the expected response. A stuck-off condition typically means line pressure stays low. You may experience slipping, soft or delayed shifts, harsh engagement, overheating, or the transmission entering limp mode.
What are the most common causes of P0746?
The most common causes of P0746 are: Low, dirty, or degraded transmission fluid, Faulty pressure control / EPC solenoid, Clogged valve body passages or stuck valve, Wiring or connector fault at the solenoid, Internal transmission wear (worn clutches, leaking seals), Dirty or clogged transmission filter, Faulty transmission control module (less common). The specific cause varies by vehicle.
How much does it cost to fix P0746?
Repair costs for P0746 range from $120 to $6,500, depending on the vehicle and root cause.
