Fits: Duramax with Allison 1000 Transmission

The Allison T3 bearing mounts under the rotating drum as it sits down in the case. This T5 bearing is used in the earlier models and mounted under the P2 sun gear from the rear of the transmission. During a transmission overhaul/rebuild, we recommend replacing the thrust washer/bearing with this Genuine Allison replacement.

Features:

• Genuine Allison Part

DmaxStore Note:
