Dura-Bond TH400 Turbo 400 Sun Gear Bushing

Quality sun gear bushing for the GM TH400 Turbo 400 3L80 automatic transmission. Dura-Bond sintered bronze designed to restore proper clearances in the heavy-duty TH400. Worn bushings are a leading cause of low line pressure and erratic shifting in high-mileage TH400 transmissions.

Replace all bushings and thrust washers during every rebuild for optimal hydraulic performance. Fits all 1964-1990 TH400 applications in Chevrolet, GMC, Pontiac, Buick, and Oldsmobile vehicles.
