The OE pump bushing in GM 6L45, 6L50, 6L80 and 6L90 transmissions utilizes a PTFE-impregnated load bearing surface to support large forces and survive dry-start conditions. Replacement bushings are unavailable from GM, so when this bushing eventually wears out, builders have the choice of buying an entire bell housing to get the bushing or settling for aftermarket bushings that can't stand up in this environment. Unfortunately, it is also very common for these units to suffer internal torque converter failures which create debris that ruins this bushing.
Sonnax PTFE-impregnated pump bushing 104034A is a direct replacement OE-style bushing which should be used in these 6L units that contain a worn bushing, or one that has been damaged because of an internal converter failure.

Sonnax bushing is impregnated with highly wear-resistant PTFE — not simply adhesive coated — providing unmatched durability
Excellent fatigue and seizure resistance
Precision fit and function assure long bushing life
