ATS Co-Pilot Transmission Controller for Jeep (2007-11) 3.8L with 42RLE

6019008320
The ATS Co-Pilot for the Jeep 42-RLE (2007 to 2011 only) is a MUST, it commands line pressure and internal clutch timing within the transmission to improve the reliability of the 42-RLE transmission by adding holding force of the clutch packs and converter clutch. Any Jeep that has over sized tires or a modified engine NEEDS the assistance of the Co-Pilot transmission controller to increase the line pressure of the transmission to adjust for higher power levels or oversized tires. The Co-Pilot will work on any transmission stock or modified, when used in conjunction with an ATS transmission or valve body maximum line pressure is achieved providing the best in transmission performance and reliability. The 42-RLE is plagued by small clutch packs, weak hard parts, a constant slip torque converter lock-up, and inadequate line pressure. Typically, these issues can result in the failure of the stock transmission with just a mild tune or larger tires. The Co-Pilot addresses these concerns.

The Co-Pilot has a huge advantage over TCM programing on 2007 to 2011 Jeeps because of the way the factory TCM is designed. We have found when aftermarket tuning for higher line pressures are done to the ECM/TCM to command higher line pressure in the transmission many if not all aftermarket TCM tuning will cause a radical pressure variation that spikes line pressure causing lots of problems. For this reason, you will find TCM tuning is not desired on the 3.8L and when TCM tuning is used many tuners do not allow for full line pressure increases like the Co-Pilot does, the Co-Pilot utilizing its dynamic closed loop control addresses this with an averaging circuit that provides a very smooth and controllable line pressure rise up to 155PSI. Clutch timing is programmed into the Co-Pilot to increase clutch pack life. On any 42-RLE transmission, clutch timing is optimized to reduce wear on clutch packs, efficiently transfer power and increase reliability.

The torque converter lock-up apply on a stock 42-RLE leaves a lot to be desired. The factory TCM will command lock-up at a very low apply rate when at light throttle, this causes a slipping condition that damages the converter clutch especially when behind a modified engine or when running over sized tires. The ATS 42-RLE Co-Pilot will more firmly lock the converter clutch during apply, this allows the inherent torque of the 3.8L engine to be used for better efficiency and performance.
