GM TH400 transmissions typically use selective thrust washers to set front endplay between the pump and forward drum. In heavy-duty and racing applications, replacing these washers with thrust bearings is a common durability upgrade. However, a suitable bearing for this location was previously unavailable. The Sonnax pump thrust bearing kit 34211-01K addresses this issue, featuring an ideal .126" thick thrust bearing and a range of shims for precise endplay adjustment in .005" increments.
