Co-Pilot TOW Edition Transmission Controller Kit for 2007.5-Present Dodge with 68RFE Transmission, Plug and Play Line Pressure Controller The 68-RFE is plagued by small clutch packs, weak hard parts, 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 heavy trailer. The Co-Pilot Tow Edition addresses these concerns.
What is the ATS 68-RFE Co-Pilot
The Co-Pilot consists of a controller, harness and secondary electronics box. The harness plugs into the main transmission connector on the valve body. The harness is completely plug and play for easy installation. The controller mounts in the cab and allows the driver view critical transmission and engine inputs such as line pressure, commanded engine loan and actual 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.
The secondary electronics box is mounted to the drivers side frame and requires no cutting or fitting.
What Does the ATS 68-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 68-RFE to 160 PSI. Unfortunately, this is not high enough to reliably prevent clutch slippage above 400hp. The Co-Pilot reads boost pressure and 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. This is all done automatically in the controller.
Line pressure is increased dramatically with the addition of a Valve Body Full Pressure Enable Kit. This kit is installed on any 68-RFE transmission built in house at ATS.
The kit can also be installed on a stock transmission to safely allow line pressure to increase to 270+ PSI. While the installation of the kit isnt 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 68-RFE Valve body.
The Co-Pilot has a huge advantage over TCM programing on 2013 and newer trucks because of the way the factory TCM is designed. When the higher line pressure modifications are done to the Valve body on a truck that is 2013 and newer aftermarket TCM tuning that is used will cause a radical pressure variation that spikes line pressure causing lots of problems. For this reason you will fine TCM tuning is not desired on these newer truck and when TCM tuning is used the 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 270PSI.
Clutch timing is programmed into the Co-Pilot and crucial to clutch pack life. On any 68-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 68-RFE leaves a lot to be desired. The factory TCM will command lock-up at a very low speed when at light throttle, this causes a sluggish condition, low boost and poor drivability. The ATS 68RFE Co-Pilot will more firmly lock the converter clutch during apply, this allows the inherent torque of the Cummins 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 percent and 5 lights=100 percent
Setting 2 (One position from far right)
This mode shows you what the Boost sensor is seeing. No Lights=0 PSI Boost and 5 lights=40 PSI Boost
Setting 3 (Two positions from the right)
This mode shows you what the actual transmission line pressure is No Lights=100 PSI line pressure and 5 lights=260 PSI Line pressure.
