Description

The Sun Coast Converters 104034A is a Sonnax pump bushing designed as a direct replacement for GM 6L45, 6L50, 6L80, and 6L90 transmissions. This bushing features a PTFE-impregnated bimetal material for wear resistance and durability, especially under dry-start conditions.

This replacement bushing is crucial as GM does not offer OE replacement bushings separately, forcing builders to choose between an entire bell housing or subpar aftermarket options. The Sonnax 104034A is designed to withstand the harsh environment often caused by internal torque converter failures that can damage the original bushing. It offers excellent fatigue and seizure resistance, ensuring long bushing life.
