Product Description
The TransGo 45RFE-HD2-A Reprogramming Kit is a proven transmission upgrade for Dodge Ram owners looking to correct common RFE transmission complaints and improve overall durability. Built for 1999-2018 applications, this kit is especially popular for 68RFE-equipped Dodge Ram trucks that need better lock-up control, quicker shifts, stronger accumulator performance, and improved transmission reliability under towing, work, and performance use. This kit addresses rough lock-up apply, TCC slip codes, converter drain-back, excessive cooler pressure, limp-in issues, and soft shifts while adding upgraded internal components designed to help extend service life.
This TransGo kit includes a new torque converter limit valve system for both early and late pumps, a heavy-duty accumulator plate/cover, recalibrated valve body accumulator springs, TransGo engineered seals, a heavy-duty snap ring for the input drum, and a replacement self-cleaning low/reverse switch valve with end plug. It is designed to deliver quicker, firmer, more consistent shifts without relying on tuning alone, making it a strong upgrade for daily driving, towing, and moderately tuned trucks.
