Sonnax TH350 Turbo 350 Rear Planet Bushing

Quality rear planetary bushing for the GM TH350 Turbo 350 automatic transmission. Manufactured by Sonnax, this set features heavy-duty bronze designed to restore proper clearances and endplay throughout the transmission. Worn bushings and thrust washers are a leading cause of pressure loss and erratic shift behavior in the TH350.

Replace all bushings and washers during every rebuild to ensure optimal fluid routing, proper shaft support, and correct endplay. This Sonnax rear planet bushing is precision-manufactured and fits all TH350 applications from 1969 to 1986 across Chevrolet, GMC, Buick, Oldsmobile, and Pontiac vehicles.
