Why Replace the Bushings? Internal bushing wear is a common contributor to 4T40E and 4T45E transmission issues including slipping between gears, delayed or harsh engagement, loss of overdrive, abnormal noise during operation, and reduced hydraulic pressure. Replacing the full bushing set during a rebuild addresses these root causes and helps prevent premature failure of clutch packs and other internal components.
