Product Description
The ATS 601-900-9272 Co-Pilot Transmission Controller is a proven upgrade for 2003-2018 Dodge and Ram applications equipped with the 545RFE, 65RFE, or 66RFE transmission behind the 5.7L HEMI. Designed to improve transmission reliability, shift control, and converter clutch holding power, the Co-Pilot helps correct the limitations of the factory control strategy under towing, oversized tire, and higher torque conditions.
The ATS Co-Pilot commands line pressure and internal clutch timing to increase clutch pack holding force and improve converter clutch apply. By taking control when additional pressure is needed, it helps reduce clutch slippage and delivers firmer, more confident transmission performance. The included harness is plug-and-play, and the in-cab controller allows the driver to monitor critical transmission and engine inputs.
This is an excellent upgrade for HEMI trucks used for towing, daily driving, or performance applications where stock line pressure and converter clutch apply can fall short under load. ATS also notes that the system works complete with harness and is designed specifically for 2003-2018 Dodge/Ram 545RFE, 65RFE, and 66RFE transmissions.
