Product Description

The aFe POWER 77-52002 ShiftLogic Transmission Module is engineered specifically for the 68RFE automatic transmission found in 2007.5-2018 Dodge/Ram 2500/3500 Cummins diesel trucks. The 68RFE is well known for its shudder, slippage, and soft shift feel at low RPM - issues that become more pronounced when power adders like tuners, intakes, or exhaust upgrades are installed. The ShiftLogic module addresses this by modifying transmission line pressure, resulting in firmer, crisper shifts and significantly reduced slippage during hard acceleration and towing.

Installation is fully plug-and-play using OE factory-style connectors that plug directly into the factory transmission harness with no cutting or splicing required. Three selectable settings - Stock, Stage 1, and Stage 2 - allow drivers to dial in shift feel based on their use case, from daily driving to heavy towing to performance applications. The lower fluid temperatures produced by reduced slippage also extend the overall life of the transmission. Compatible with stock and modified 68RFE transmissions, this module pairs well with other aFe POWER products and virtually any performance combination.
