SunCoast Shift Correction Package E40D/4R100 Transmission 89-02 Ford 7.3L Powerstroke WT-456071 like all Mishimoto's Powerstroke performanceSunCoast Performance has a passion for making drivetrains in diesels run at their peak. It's no different with the 89 02 Ford E40D and 4R100. Known for slipping during shift events, SunCoast combats this shortcoming by replacing the original equipment's plastic drain back valve with a metal valve. By replacing the valve, the chance of it melting and blocking lubrication to the overdrive planetary gears is removed, preventing premature failure.
