JF011E / RE0F10A CVT valve body with solenoids, filter, screen and pan gasket for Jeep Compass, Dodge Caliber and Mitsubishi Outlander.
Jeep Compass and Patriot owners know the JF011E CVT by its habits: a shudder rolling away from a stop, a lazy or flaring engagement into Drive, and a car that suddenly holds one ratio and refuses to pull. This reconditioned valve body kit is aimed squarely at the Chrysler and Mitsubishi side of the family, where Chrysler called the unit the CVT2. It cross-references 31705-1XF1A, 31705-1XF0C and 31705-3TX0C and ships with the solenoids installed, a transmission filter, an oil filter with O-ring, and the oil pan gasket.
Inside the Compass, Patriot and Caliber transaxle, the belt and two variable pulleys give the ratio, but the valve body gives the belt its grip. Its solenoids regulate line pressure, primary and secondary pulley pressure, and converter clutch apply, while the step motor and ratio-control valve move the pulleys toward the ratio the TCM wants. Worn bores leak that pressure away. Sonnax notes that when the torque converter pressure regulator bore wears, apply pressure goes erratic and the result is converter shudder - exactly the low-speed vibration many Patriot owners describe.
Pull codes and look at the fluid first. Dark fluid with fine metal on the magnet suggests the belt or pulleys have already been chewed up, and no valve body will bring that back; a JF011E rebuild kit for Caliber and Patriot is the honest fix there. If the fluid is reasonably clean and the fault is pressure-related, the valve body is the target. Our CVT limp mode guide explains how to read the codes that drop these vehicles into fail-safe, and the harsh or delayed shifts walkthrough covers the Drive and Reverse delay test.
The listing covers the Mitsubishi Lancer 2008-2015, Outlander 2008-2017 and Outlander Sport 2011-2017, the Dodge Caliber 2007-2012, and the Jeep Compass and Patriot 2007-2017, all with the JF011E. Jatco built several closely related bodies across this family and they are not all interchangeable, so read the number on your current valve body and match it to the references above. Compass and Patriot were also sold with manual and conventional automatic transmissions, so confirm a CVT is in the vehicle. If the numbers do not line up, send us your year and VIN, or compare other bodies in our CVT parts collection.
Transmission Digest's bench tips for this unit come straight from a Dodge Caliber example: keep the original ROM with the vehicle, because a ROM from another unit triggers P167A and Chrysler-side reprogramming is the only other way out. Tag the ROM so it does not get mixed up with the core. Unplug the internal harness, pull the manual lever and its sleeve, then hold the pulley-ratio lever with a 3 mm rod through the access hole before you lift the body off its eleven bolts. Install the new filters and gasket from this kit, and fill with the fluid your vehicle specifies - Chrysler CVTF+4 for Jeep and Dodge, the Mitsubishi or Nissan-spec CVT fluid for others. Because this unit is reconditioned it may show light cosmetic marks; that does not affect function. If the fluid was contaminated, pair the job with a JF011E transmission cooler to keep temperatures down on a Patriot that tows or climbs.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It fits Compass and Patriot models built with the JF011E CVT. Models with a manual or the conventional automatic do not use it. Match the number on your existing valve body to 31705-1XF1A, 31705-1XF0C or 31705-3TX0C.
On Dodge applications it flags a calibration mismatch between the ROM chip on the internal harness and the TCM. Reinstall the original ROM from your vehicle and the code should clear.
Use the CVT fluid your vehicle calls for: Chrysler CVTF+4 for Jeep and Dodge, and the matching Mitsubishi or Nissan-spec fluid for those models. Do not use a generic multi-vehicle ATF.
It is reconditioned, with the solenoids installed. It may carry light cosmetic marks from refurbishing.
The filters and pan gasket are included. If you see metal in the pan, inspect the belt and pulleys before installing, and consider an auxiliary cooler if the vehicle runs hot.
