    Beef Up Your Jeep’s Transmission. When modifying a Jeep Wrangler, most people jump directly into appearance and off-road performance modifications, opting for a lift kit, larger tires, and heavy off-road bumpers. Without any supporting mods, especially with serious off-road abuse, towing, or an increase in HP, it’s not uncommon for your Jeep’s factory 42RLE automatic transmission to let go, leaving you stranded. If this sounds like your current predicament, then ATS Diesel has the perfect solution for you. This upgraded 42RLE Automatic Transmission Package is the ideal way to beef up your Jeep’s drivetrain, providing an upgraded transmission modified internals and a premium TruLok billet torque converter to significantly improve durability and performance. 

    TruLok Torque Converter. This transmission package includes an ATS Diesel premium TruLok billet torque converter for additional performance gains and enhanced durability. Unlike your Jeep’s factory stamped-steel converter, this performance billet converter is built to last, featuring a heavy-duty billet casing that won’t flex under load. As a result, converter clutch slip is kept to a minimum, extending the life of both the converter and the transmission’s internals.

    Heavy-Duty Clutches. This transmission utilizes heavy-duty, upgraded carbon-composite clutches for maximum holding power, reducing clutch slip and preventing excess clutch material from flooding your Jeep’s transmission fluid. 

    Modified Valve Body. The valve body is the transmission's brain, interpreting signals from the computer to adjust line pressure and several other variables in the transmission. In factory form, your Jeep’s factory valve body is less-than-satisfactory, capping line pressure at a low level to prevent harsh shifting at full throttle; however, with an increased load, this lack of line pressure can cause the transmission to slip. For this reason, ATS installs a heavily-modified valve body into each 42RLE transmission. 

    Warranty. A 5-Year/500,000-mile warranty covers this product against manufacturing defects. 

    Application. This ATS Diesel 42RLE Automatic Transmission Package fits 2007-2011 Jeep Wrangler 3.8L models.
