Worn babbit pump bushings in GM Powerglide, 350, 400 and Allison® AT540 units allow the converter hub and inner pump gear to move off-center, causing damage to the pump gears and pump housing crescent. This Sonnax pump bushing 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
