42RLE Rebuilt Transmission

About the 42RLE Transmission

The 42RLE transmission is a 4-speed automatic transmission developed by Chrysler, designed primarily for front-wheel-drive and rear-wheel-drive applications. Introduced in the early 2000s, it was widely used in Jeep, Dodge, and Chrysler vehicles, including popular models like the Jeep Wrangler, Jeep Liberty, Dodge Dakota, and Chrysler Sebring. The 42RLE was designed as a versatile transmission, suitable for everyday driving as well as off-road applications, particularly in Jeep models.

The 42RLE features a hydraulically controlled system with electronic enhancements that allow for smoother shifts and better adaptability to driving conditions. Its design includes planetary gearsets, a lock-up torque converter, and a lightweight aluminum casing to improve efficiency and reduce overall vehicle weight. This transmission also utilizes adaptive shift logic, enabling it to adjust shift points based on driving behavior. While simple in its construction compared to modern multi-speed transmissions, the 42RLE is known for its durability and ease of maintenance.

Despite its strengths, the 42RLE has been associated with several common issues over its lifespan. One frequent problem is overheating, especially in vehicles used for towing or off-road driving, where the transmission is subjected to higher stress. Other issues include delayed or harsh shifting, often caused by worn solenoids, valve body wear, or low-quality transmission fluid. Over time, these problems can lead to more severe issues, such as torque converter failure or internal component wear, particularly if the transmission is not maintained properly.

Remanufactured 42RLE transmissions have become a popular solution for addressing these shortcomings. Modern remanufacturing processes replace worn or defective components and often include upgrades to address factory defects. For example, remanufactured units may include improved torque converters, upgraded clutches, and enhanced valve bodies to improve reliability and performance. Rigorous testing ensures that these units meet or exceed original specifications, making them a superior alternative to rebuilt or used transmissions.

The 42RLE remains a reliable and widely used transmission, especially in the Jeep community, where its ability to handle off-road conditions is highly valued. Although it has been succeeded by newer designs with more gears and advanced technologies, the 42RLE continues to serve as a dependable option for older vehicles. Proper maintenance, such as regular fluid changes and the addition of auxiliary transmission coolers, can extend the life of the 42RLE and help it perform reliably in demanding conditions.

The transmission is one of the most critical components of your vehicle, second only to the engine. If your 42RLE transmission is showing signs of failure, the best solution is a high-quality remanufactured 42RLE transmission from Certified Transmission. While used or rebuilt options may seem appealing at first, Certified's remanufactured transmissions go beyond standard expectations to deliver exceptional performance, reliability, and longevity.

Why Remanufactured is Better Than Rebuilt or Used

A used 42RLE transmission is simply a salvaged unit pulled from another vehicle. While used transmissions can be economical, they come with unknown wear and tear and limited guarantees. Similarly, a rebuilt transmission typically involves replacing only the parts that have failed, leaving other components untouched. This often results in a solution that works for the short term but lacks the durability you need for long-term peace of mind.

At Certified Transmission, our remanufactured 42RLE transmissions are rebuilt to a higher standard, ensuring every unit is as close to new as possible. Unlike a basic rebuild, remanufacturing involves completely disassembling the transmission, inspecting each component, and replacing or upgrading all worn or damaged parts with OEM-quality components. The result? A transmission that performs better and lasts longer than rebuilt or used options.
