Description
SunCoast 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.
