What is the ATS 545-RFE Co-Pilot?
The Co-Pilot consists of a controller, coil box and wiring harness. The harness plugs into the transmission connector located on the side of the transmission. 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 545-RFE 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 545-RFE to 110 PSI. Unfortunately, this is not high enough to reliably prevent clutch slippage at higher power levels. The Co-Pilot senses throttle position to quickly takes 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 545-RFE Valve body. The Co-Pilot has a huge advantage over TCM programing on 2003 to 2018 TCMs because of the way the factory TCM is designed. We have found when aftermarket tuning for higher line pressures are done to the 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 causally 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. ng lots of problems. For this reason, we have found TCM tuning is not the best choice for the 545-RFE Transmission. The Co-Pilot utilizing a dynamic closed loop control addresses these issues by incorporating an averaging circuit that provides a very smooth and controllable line pressure rise up to 175PSI. Clutch timing is programmed into the Co-Pilot to increase clutch pack life. On any 545-RFE 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 545-RFE leaves a lot to be desired. The factory TCM will command lock-up at a very low apply rate when at higher throttle levels, this causes a slipping condition that damages the converter clutch especially when behind a modified engine or when running over sized tires. The ATS 545-RFE Co-Pilot will more firmly lock the converter clutch during apply, this allows the inherent torque of the engine to be used for better efficiency and performance.

Starting back 2 years ago I was searching for a reputable transmission shop for my 2014 Ram 3500 6.4l Hemi 4wd. The gentlemen at Arrington performance told me to checkout ATS, since I have grown to trust Arrington it was a no brainer to give ATS a shot. My first purchase was the Thermal Delete block so I could run my trans at cooler temps, not only was this product easy to install the instructions were well detailed and in color. I had inquired with the sales team if they were going to make a CoPilot for the 66RFE they replied it was actually In Research and development and soon to be released. I soon there after that bought the CoPilot and since then I have been impressed with how much better my truck pulls my 5th Wheel. Recently when my Shift Solenoid went out I purchased the complete valve body with channel plate and solenoid pack. Not only did the sales team go above and beyond again to help me, the tech support guys answered my questions about the install.
