About the Dodge Nitro Transmission
This is the 42RLE, the Chrysler 4-speed automatic transmission used in the Dodge Nitro and shared across several Dodge, Jeep, and Chrysler vehicles, as the live page describes. It is electronically controlled, housed in a lightweight aluminum case that helps dissipate heat, and uses a lockup torque converter to improve fuel economy and reduce heat during highway cruising. It is built to handle SUV duty with smooth, adaptive shifts, and it works with rear-wheel-drive and four-wheel-drive Nitro models.
Why Nitro Owners Replace the Transmission
Slipping between gears, harsh or delayed shifting, and fluid leaks, the common 42RLE failure signs noted in the live FAQ, are the usual reasons. A sound replacement restores precise, fluid gear changes, brings back quiet low-rpm highway cruising through the lockup converter, and returns the original factory feel without slipping or hard shifts.
Things to Confirm Before Ordering
- Your model year, confirmed by VIN; the page lists no year, and the Nitro ran 2007 to 2011
- Your engine pairing: this is the 3.7L V6 unit, so we confirm the engine-and-transmission match by VIN, since the 4.0L V6 typically used a different transmission
- Your fluid: per the live FAQ, the 42RLE requires ATF+4 automatic transmission fluid, and it should be installed by a qualified mechanic
