Worn babbit pump bushings in GM Powerglide, TH350, TH400 and Allison® AT-540 series transmissions allow the converter hub and inner pump gear to move off-center, causing damage to the pump gears and pump housing crescent. Sonnax pump bushing 34034T-01 is a direct replacement part that is better fitting than OE. Extremely wear-resistant, this PTFE-lined bushing helps maximize the life of these older and increasingly rare pumps.

Highly wear-resistant PTFE lining for maximum durability

Tight tolerance for improved fit

Longer pump life

Direct replacement part with no machining required
