Description, Q&A, Specs & Installation
Enhance the performance and longevity of your transmission with the PSI Power 70048 Transmission Edition module, designed specifically for 2003–2007 Dodge/RAM 2500/3500 trucks equipped with the L6-5.9L Cummins engine and 48RFE transmission.
This module significantly improves transmission shift feel by modifying line pressure, resulting in firmer shifts, reduced slippage, lower fluid temperatures, and an extended transmission lifespan.
With three customizable settings (Stock, Stage 1, Stage 2), you can tailor your driving experience using the included rotary switch. Installation is quick and straightforward, thanks to the plug-and-play design and OE factory-style connectors—no cutting or splicing required!
Compatible with other PSI Power performance products, the PSI Power Transmission Edition module is perfect for both street performance and towing applications. Unlock your truck's full potential with this easy-to-install, high-performance solution!
