Complete JF011E CVT valve body with stepper motor, solenoids, harness and two pressure sensors for Nissan, Dodge, Jeep and Mitsubishi.
A 2007-2012 Dodge Caliber, Jeep Compass or Patriot, Mitsubishi Lancer, Outlander or Outlander Sport, or a 2007-2016 Nissan Altima or Rogue that shudders at light throttle, hangs before dropping into gear, or has thrown a ratio-control or pressure-sensor fault is almost always pointing at the JF011E valve body rather than the belt or pulleys. This is a complete assembly - casting, solenoid pack, ratio-control stepper motor, internal wiring harness, and both line pressure sensors already fitted - so you install one known-good unit instead of pulling electronics off the failed body and hoping they still test in spec.
The JF011E (sold under Nissan's RE0F10A and Mitsubishi's F1CJA designations) is a belt-and-pulley CVT, and the valve body is its hydraulic and electronic control center. It routes line pressure to the primary and secondary pulleys and the forward clutch, carries the shift and pressure-control solenoids, and uses the stepper motor to set the pressure split between the two pulleys so the belt rides at the correct ratio for road speed and load. The two pressure sensors report actual line pressure back to the TCM so it can trim solenoid duty cycle in real time.
Sonnax's tech data on this transmission family ties two separate failure modes to these symptoms: wear in the primary pressure regulator bore reduces line pressure control and shows up as chatter on acceleration, pulley breakage risk, or line pressure reading high or low, while separate wear at the torque converter pressure regulator bore causes the TCC apply and release problems, erratic apply pressure, and shudder or slip at cruise. Both point at the valve body casting rather than a sensor or solenoid alone, which is why a worn JF011E body gets replaced as a complete unit instead of parted out. Before you order, drop the pan and count the pressure sensors on the unit already in the car - this is the dual-sensor version, and a single-sensor car will throw pressure sensor codes if you install the wrong one.
This valve body fits the 2007-2012 Dodge Caliber (1.8L, 2.0L, 2.4L), 2007-2010 Jeep Compass and Patriot (2.0L, 2.4L), 2007-2016 Mitsubishi Lancer (2.0L, 2.4L), 2008-2016 Outlander (2.4L), 2011-2016 Outlander Sport (2.0L, 2.4L), 2007-2013 Nissan Altima 2.5L, and 2008-2015 Nissan Rogue 2.5L. See the full CVT parts collection for the rest of what we stock for this transmission family, including filter and gasket kits, clutch hardware and overhaul kits.
Drop the pan, pull the filter, unplug the internal harness at the case connector, then unbolt the valve body in a cross pattern and support it as it comes free so the stepper motor does not drag against the case. Transfer nothing from the old unit - this one ships complete. While the pan is down, check the output speed sensor if it was disturbed: Transmission Digest's bench-tips coverage of this transmission notes the sensor rides on a 0.040-inch shim that sets its air gap, and a sensor reinstalled without that shim sits too close to the gear and will set a code or get damaged. Install a fresh filter and pan gasket kit at the same time so debris from the old body does not circulate through the new one, torque the bolts evenly, and refill with genuine Nissan NS-2 or NS-3 CVT fluid, Mitsubishi CVTF-J1, or Mopar CVTF+4 depending on the vehicle - never conventional ATF. Finish with the CVT fluid deterioration counter reset and a relearn drive. If the forward clutch module or belt is also worn, or you are already this far into the transmission, pair this valve body with a full JF011E overhaul kit rather than reassembling around parts that are close to their own failure point.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Drop the transmission pan and count the pressure sensors mounted on the valve body before you order. This listing is the dual-sensor version; installing it on a single-sensor car will set pressure sensor fault codes.
No. This unit ships complete with the casting, solenoid pack, ratio-control stepper motor, internal wiring harness, and both pressure sensors already installed.
Genuine Nissan NS-2 or NS-3 CVT fluid, Mitsubishi CVTF-J1, or Mopar CVTF+4 depending on the vehicle. Conventional ATF is not a substitute in this CVT.
Shudder with clean codes often traces to wear at the torque converter pressure regulator bore inside the valve body, which lets apply pressure escape and causes erratic TCC control. Replacing the complete valve body addresses that bore wear along with the solenoids and stepper motor.
Yes - note the stepper motor position on the new unit before you unbolt the old one and match it during installation, then complete a relearn drive so the TCM adapts to the new solenoid and stepper characteristics.
A fresh filter and pan gasket so debris from the old body does not circulate through the new one, and fresh CVT fluid. If the forward clutch or belt also show wear, an overhaul kit is more cost-effective than replacing parts one at a time.
