Description
Part Description
This transfer case assembly was removed from a 2012 GM Silverado 2500 pickup truck equipped with a 6.0L engine and automatic transmission. The unit features electric shift operation with dash switch control and is designed for 4WD applications. Our technicians have inspected this transfer case and it is currently on the shelf ready to ship.
Transfer cases are critical components in 4WD vehicles that distribute power between the front and rear axles. Common reasons for replacement include internal gear wear, chain stretch, bearing failure, or case cracking from age and high use. The electric shift mechanism can also fail over time, requiring complete transfer case replacement to restore proper 4WD operation.
