View Instructions

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. Sonnax pump bushing 34034T-01 is a direct replacement part that is better fitting than OE. Extremely wear-resistant, this PTFE-lined Kryptonite 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 (including Allison Part No. 29511860)
  • Bushing Style: Precision
  • Material: Steel-backed bimetal
  • Width: 0.615"
  • Shaft Dia.: 1.873"
  • Housing Bore: 2.001"
