The factory pump is not capable of producing enough line pressure, and it somehow bleeds off in all forward gears. Let's take a quick look at some key issues addressed: Unfortunately, the factory configuration is not capable of achieving this. Our engineers were able to determine the amount of clamping force needed to make the clutches hold. The 68RFE pump was the first problematic area that we addressed. There are several key issues with the 68RFE that contribute to the pre-mature failure of the overdrive clutches. We started researching this project with a clean slate. This base package is good for up to 600hp with the addition of a few key hard parts, such as the billet flexplate and billet input shaft, which is highly recommended.The M3GA JR 68RFE unit is specifically designed to eliminate the dreaded overdrive issues. This unit is also capable of a mildly modified street performance machine. When coupled with one of our towing triple disc billet torque converters, you will not find a more efficient transmission on the planet at any cost. It works incredibly well as a towing unit for hot-shot driving, 5th wheel motorhomes, and most anything else you can hook up to the back end. transmission is a perfect solution for a deleted, mildly modified truck that can serve as a dual purpose unit. ![]() SunCoast Custom Billet C4 spring retainer.SunCoast Custom patented Billet L/R Sprag.SunCoast Custom designed overdrive/ underdrive powerpack.SunCoast Custom designed clutch stack ups for all other clutch packs.SunCoast Custom designed 2C apply plate.SunCoast Custom machined billet apply plate. ![]() SunCoast Custom machined Billet Overdrive Accumalator piston.SunCoast Custom water jetted seperator plate.SunCoast Custom TC limit Valve modification. ![]() SunCoast Custom Patented M3GA full comp billet drum. ![]()
