The Chrysler Jeep 42RE automatic transmission, specifically designed for the Cherokee Wagoneer, is a robust and reliable unit known for its ability to handle the demands of off-road driving and towing. Introduced in 1987 and continuing production until 1998, the 42RE became a cornerstone of the Wagoneer's success. It's a three-speed automatic transmission with a torque converter, featuring a unique design that combines durability with smooth shifting. The 42RE is well-known for its ability to handle high torque output, crucial for the Wagoneer's powerful engine options. The transmission utilizes a planetary gearset, which allows for multiple gear ratios within a single unit, making it compact and efficient. The 42RE also features a lock-up torque converter, offering improved fuel economy and increased performance during highway driving. This transmission was specifically designed to handle the demands of off-road driving, featuring a strong internal build and a robust case. The 42RE's reputation for reliability and durability has made it a popular choice for off-road enthusiasts and those who rely on their Wagoneers for heavy-duty towing. However, like any mechanical component, the 42RE is susceptible to wear and tear. Common issues include slipping gears, rough shifting, and internal leaks. Regular maintenance, including fluid changes and filter replacements, is essential for maximizing the lifespan of this transmission. Despite its inherent robustness, the 42RE is a relatively simple transmission compared to modern automatics. It lacks features like electronic control units (ECUs) and multiple overdrive gears, which can be viewed as both a benefit and a drawback. While it may not offer the fuel efficiency or performance of modern transmissions, the simplicity of the 42RE makes it relatively easy to repair and maintain, contributing to its enduring popularity within the Jeep community.
