ATS Diesel 6019009272 Co-Pilot Transmission Pressure Controller for 545RFE with Harness

The ATS Diesel Co-Pilot Transmission Controller is an essential upgrade for 2003-2012 Dodge Ram trucks and 2003-2012 Jeep Grand Cherokee vehicles equipped with HEMI engines and 545RFE transmissions. This plug-and-play controller addresses the factory transmission's inadequate line pressure and clutch pack weaknesses that commonly lead to transmission failure with modified engines or oversized tires.

What It Does:

• Commands line pressure and internal clutch timing to improve transmission reliability
• Increases clutch pack holding force and converter clutch engagement
• Senses throttle position to quickly control line pressure when needed
• Raises maximum line pressure from stock 110 PSI to 155 PSI
• More aggressively applies the converter clutch under high torque situations

Complete Kit Includes:

• In-cab controller with LED display
• Coil box electronics module
• Plug-and-play wiring harness

Key Features:

• In-cab controller displays transmission line pressure, TPS position, and engine load data
• Adjustable settings via up/down arrows on controller face
• Multiple viewing modes for real-time transmission diagnostics
• Completely plug-and-play installation - harness connects to transmission-side connector
• Settings adjustable on-the-fly or while stopped

The Co-Pilot is specifically designed for vehicles with heavily modified engines, turbo/supercharged applications, oversized tires, or increased towing demands. It prevents the transmission failures that commonly occur during forced downshifts under full power by providing the necessary clutch pack pressure to handle increased torque loads. Works with stock or modified transmissions, and achieves maximum performance when paired with ATS valve bodies.
