47/48re DIY rebuild kit

This complete rebuild kit is designed for durability, performance, and proper clutch clearance. Featuring premium friction materials from Raybestos, BorgWarner, and Alto, along with upgraded hard parts, this kit provides the reliability and holding power needed for street, towing, and performance applications.

Engineered with proven components and tested combinations, it includes everything required to reseal and refresh your transmission with confidence.

Our kit offers a brand-new Sonnax overdrive piston support—one of the most critical upgrades available. This component alone is a major reason our kit costs more than others, delivering superior durability and long-term reliability that budget kits simply don’t offer.

Due to manufacturer lead times, this rebuild kit may include BorgWarner friction materials in place of Raybestos GPZ frictions. This substitution does not reduce the quality, performance, or reliability of the rebuild kit.
