12-piece master transmission bushing kit for GM 6L-family automatic transmission repair and rebuild applications.

About This Kit

Transmission bushings support rotating shafts and help maintain proper alignment inside the transmission. Worn bushings can contribute to shaft movement, fluid-pressure concerns, and shift-quality issues. Replace worn or damaged bushings during a transmission rebuild when inspection confirms they require replacement.

Installation Guidance

This bushing kit is intended for professional transmission rebuilding and repair. Have a qualified installer inspect mating shafts, bores, seals, and lubrication passages, then follow the applicable service procedures for bushing installation and clearances.
