JF017E Internal Wiring Harness 2013, used and ready to install. Fits the JF017E. Ships fast from the USA.
A 2013 Altima 3.5 or Pathfinder that drops into fail-safe, logs a pressure sensor or solenoid circuit code, then drives fine after a restart is often telling you about wiring, not a dead transmission. The JF017E, Nissan's RE0F10E, routes every solenoid and sensor inside the case through a single internal harness. This is a used OEM internal wiring harness taken from a 2013 JF017E, so you can replace a harness with broken insulation, a loose terminal or a failed connector seal without paying for a valve body you may not need.
The JF017E is the heavy-duty, chain-drive CVT Jatco built for Nissan's 3.5L V6. Unlike the older JF011E there is no stepper motor; ratio is controlled entirely by solenoids. On the upper valve body sit the line pressure, primary pressure and secondary pressure linear solenoids, the select solenoid that controls engagement feel, and the TCC solenoid that manages lockup slip. Two pressure sensors on top of the valve body report primary and secondary pressure back to the TCM. The solenoid grounds are made through the valve body itself. The internal harness ties all of these to the case connector, so an open or corroded wire shows up as a solenoid or sensor fault even when the part itself is good. The input, primary and secondary speed sensors are mounted externally and do not run through this harness.
The JF017E's best-known failures are still mechanical: chain and pulley wear that causes shudder, valve body wear, and heat. A harness corrects electrical faults only. If your codes are ratio or performance codes with no circuit codes alongside them, look at the hydraulics first.
Check resistance through the case connector, then at each solenoid with the pan down. Published specs for this unit are 5.5 to 8.5 ohms for the pressure and select solenoids and 6.1 to 7.7 ohms for the TCC solenoid. A good reading at the solenoid and an open or high reading through the connector condemns the harness. Watch live pressure sensor data while wiggling the case connector; dropouts point at the harness too. See our guides on solenoid testing without a factory scan tool and reading transmission live data.
This harness was removed from a 2013 JF017E. In 2013 that transmission was installed behind the 3.5L V6 in the Nissan Altima and Pathfinder; later the same family went into the 2015 and newer Murano and Quest and the Infiniti QX60. Nissan revised parts across those years, and this harness was sourced under a listing that also references the JF016E, so treat the year and model name as a starting point, not a guarantee. Match the case connector, the number of solenoid and sensor plugs, and their colors against your old harness, or send us your year and VIN before ordering. Browse the rest of our Jatco stock on the CVT parts page.
If the valve body is already on the bench, it is a good time to replace worn electrical parts with a JF017E 7-piece solenoid kit, or swap in a JF017E valve body if the bores are worn. A replacement valve body needs its calibration data loaded into the TCM.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
In 2013 the JF017E (RE0F10E) was used with the 3.5L V6 in the Nissan Altima and Pathfinder. The four-cylinder Altima uses the JF016E instead.
No. On the JF017E the input, primary and secondary speed sensors mount on the outside of the case and have their own wiring. This harness serves the valve body solenoids and the two pressure sensors.
The two units are close relatives and this harness was listed against both, but Nissan revised harnesses by model and year. Compare the connector and plug layout with your old part or send your VIN before ordering.
Roughly 5.5 to 8.5 ohms for the pressure and select solenoids and 6.1 to 7.7 ohms for the TCC solenoid. An open or much higher reading through the connector, with a good reading at the solenoid, points at the harness.
