JF017E Valve Body, new and ready to install. Fits the JF017E. Ships fast from the USA.
If your V6 Pathfinder, Murano, Maxima, or Infiniti QX60 is jerking on coastdown, stalling on engagement, running hot, or will not hold torque converter lock-up, the valve body on the JF017E CVT is the usual cause once fluid level and condition have been ruled out. The JF017E is the V6 half of Nissan's second-generation CVT family and carries its own valve body wear patterns separate from the 4-cylinder JF016E.
Nissan builds the JF016E (4-cylinder, also coded RE0F10D) and JF017E (V6, also coded RE0F10E) side by side, and both route pump pressure through the same style of valve body to apply the torque converter clutch and clamp the belt against the primary and secondary pulleys. The valve body carries the main pressure regulator, the torque converter lube regulator valve train, the lock-up control circuit, and the pulley reducing valves that set clamping force, along with the solenoids the TCM uses to command all of it.
Rule out fluid condition and level first, since both the JF016E and JF017E are sensitive to old or incorrect fluid. From there, our CVT slipping under load guide covers separating a valve body pressure problem from belt or pulley wear, and our CVT limp mode diagnostic guide walks through reading the stored codes before you replace a part this expensive on a guess.
This valve body fits the JF017E as installed behind the V6 in the Nissan Pathfinder, Murano, Maxima, and the Infiniti QX60, model years 2013 and up. The JF017E is not interchangeable with the 4-cylinder JF016E valve body even though the two transmissions share a family design, so confirm your transmission code (RE0F10E for the JF017E, RE0F10D for the JF016E) stamped on the unit before ordering, or send your year, make, model and VIN and we will match it. Browse the CVT parts collection to compare against the 4-cylinder JF016E valve body if you are not certain which engine you have.
Drop the pan and inspect the fluid condition before pulling the valve body - dark or metallic fluid points to pump or pulley wear beyond the valve body and changes the repair plan. Transfer the internal harness and torque the valve body bolts in the manufacturer's sequence rather than a spiral pattern, since an uneven bolt-down can introduce a new leak or pressure complaint on a unit that was fine before the swap. Refill with Nissan NS-3 CVT fluid and run the TCM relearn and a full drive cycle before calling the job done. Pair this valve body with a fresh JF017E solenoid kit if your old solenoids are original-mileage, and check the CVT pump while the unit is open if your pressure test showed low base line pressure.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 4-cylinder cars use the JF016E (RE0F10D), a related but separate transmission with its own valve body. This listing is for the JF017E (RE0F10E) built behind the V6 in the Pathfinder, Murano, Maxima, and Infiniti QX60.
Jerking on coastdown on this CVT family is commonly traced to wear in the torque converter lube regulator valve train inside the valve body, which lets fluid bleed off the circuit. It is one of the most consistent symptoms pointing at this valve body rather than the belt or pulleys.
This listing is a new valve body, not a remanufactured core exchange.
Nissan NS-3 CVT fluid. Running the wrong fluid or skipping a fluid change at the recommended interval is a major contributor to the pressure-related failures this valve body addresses.
Not necessarily, but if your solenoids are original-mileage or you were also seeing solenoid performance codes alongside the mechanical symptoms, replacing them together avoids reusing a worn solenoid on a fresh valve body.
