42RLE Valve Body, used and ready to install. Fits the 42RLE. Ships fast from the USA.
A Jeep Wrangler, Liberty or Dodge Nitro running the 42RLE that bangs into gear, flares between shifts, or drops into limp mode with a stored solenoid code almost always needs attention at the valve body before the clutch packs behind it are to blame. This used OEM valve body was pulled from a running 42RLE and tested, so you get a known-good part without paying remanufactured pricing while you track down a shift complaint.
The 42RLE is Chrysler's rear-wheel-drive-based four-speed automatic. It's hydraulically controlled but shifted under electronic command from the transmission control module, the same basic strategy Chrysler used on the front-wheel-drive 41TE. The valve body is where that command becomes motion: it directs line pressure through its bores and spool valves to apply the low/reverse, 2-4, overdrive and underdrive clutches, while the shift and governor pressure solenoids mounted to the body execute whatever the computer sends them. When a bore wears or a solenoid sticks, pressure leaks past a clutch that should be holding, and shift quality degrades even when the clutch packs are otherwise fine.
The 42RLE's transmission control module tracks an adaptive Clutch Volume Index for each clutch pack, so pull codes and check those values before ordering parts. A high CVI on a specific clutch points at that clutch, not the valve body; a solenoid, pressure or ratio-error code with otherwise normal CVIs points at the valve body and its solenoids instead. Our Chrysler Ultradrive problems guide and slipping under load guide cover the same CVI-based diagnosis Chrysler built into both the 41TE and 42RLE control strategy.
This listing doesn't carry a model year because the 42RLE's hydraulic layout stayed largely the same across the Jeep Wrangler TJ and JK, Jeep Liberty KJ, and Dodge Nitro for most of its production run, though Chrysler still revised solenoid connectors and casting details along the way. Match the casting number and connector style stamped on your old valve body, or send us your year, make, model and VIN before ordering so we can confirm the exact version your application needs. Every 41TE/42RLE-family part we stock is on the 41TE parts page.
Drop the pan and service the fluid and filter together with a 42RLE filter and pan gasket kit so debris from the failed valve body doesn't carry over into the replacement. If the transmission is also slow to build pressure at idle, check the 41TE/42RLE pump while the pan is down, since a worn pump will starve even a good valve body of the pressure it needs. Torque the valve body bolts in sequence to spec, refill with ATF+4, and run the transmission through every gear a few times so the adaptive controller relearns against the new part.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 42RLE's hydraulic layout stayed largely the same across most of its production run in the Jeep Wrangler, Liberty and Dodge Nitro, so this valve body covers a wide span of years. Match the casting number and connector on your old unit, or send your VIN, to confirm the exact fit.
The Jeep Wrangler TJ and JK, Jeep Liberty KJ, and Dodge Nitro all used the 42RLE.
It's a used OEM valve body, pulled from a running 42RLE and tested before listing.
ATF+4 only.
Pull stored codes and Clutch Volume Index values. A high CVI on one clutch points at that clutch; solenoid or pressure codes with normal CVIs point at the valve body.
Service the filter and pan gasket together, and check the pump if you're seeing slow pressure buildup or shift delay complaints alongside the valve body symptoms.
