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.

What is the ATS 42-RLE Co-Pilot?
The Co-Pilot consists of a controller and wiring harness. The harness plugs into the TCM connector on the main computer located in the engine compartment. The harness is completely plug and play for easy installation. The controller mounts in the cab and allows the driver to view critical transmission and engine inputs such as line pressure and commanded engine load. To view the different sensor inputs all you do is depress the up or down arrows. These changes can be made on-the-fly or with the vehicle stopped.

What Does the ATS 42-RLE Co-Pilot Do?
The Co-Pilot controls line pressure, clutch timing and more aggressively applies the converter clutch under high torque situations. Line pressure is limited in a stock 42-RLE to 90 PSI. Unfortunately, this is not high enough to reliably prevent clutch slippage at higher power levels. The Co-Pilot senses throttle position to quickly take control of line pressure when it is needed. However, when the vehicle is driven lightly, line pressure is near stock for comfortable shifts and lower transmission temperatures. This is all done automatically in the controller. Line pressure is increased more dramatically and lubrication pressure is increased with the addition of an ATS Valve Body. While the ATS valve body installation isn't necessary, it will increase the performance of the Co-Pilot to its fullest potential. We recommend installing one of our modified valve bodies to fully address all of the internal hydraulic issues with the stock 42-RLE Valve body. 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.

Modes Available in Co-Pilot:
  • Setting 1 (down or all the way to the right) This mode shows you what the position of the TPS is. No Lights=0% and 5 lights=100%
  • Setting 2 (Two positions from the right) This mode shows you what the actual transmission line pressure is No Lights=70 PSI line pressure and 5 lights=155 PSI Line pressure.

  • Co-polit how does it work and how do I use it do I only use it when towing?

    The ATS CoPilot provide you the ultimate in push-button control over when the torque converter locks up in your vehicle, allowing you to select the vehicle speed where the torque converter clutch will engage (lock up) and disengage. Your truck's factory programming doesn't initiate lock up until cruising speed and disengages lock up early under many conditions, inhibiting your truck's performance. The Commander and Co-Pilot resolve this issue by holding lock up offering better acceleration and cooler transmission running temperatures.

  • Will it work with out a ecm? Thanks

    No

  • I recently bought an ats stage 3 from you folks for my 01 dodge 3500. I’ve hooked up the copilot and doesn’t seam to do anything other than my converter won’t lock up at all. And when I shut the controller off I lose my speedometer. I’ve double checked all my connections and I don’t run any other programmer. Computer has never been touched. I’ve owned this truck since it was new. Any suggestions would be great.
