Transmissions

The LBZ transmission category is mostly Allison support, not a general LBZ engine page. Transmission cooler lines, transmission coolers, filters, pans, and converters are the parts owners usually need here.

This category support parts for 2006-2007 Duramax trucks include cooler lines, transmission coolers, filters, pans, and converters. Leaking cooler lines are common enough that many owners replace them before they become a roadside problem.
