Transfer Case – GM (19133140)

Transfer Case holds, shields or mounts other components in the assembly. Bolt spacing and depth are what decide fitment, and neither is visible without measuring.

Replace the Transfer Case when the bolt holes have elongated, when the gasket surface is pitted, or when the part has distorted from heat. A warped flange leaks with any gasket.

This Transfer Case is listed as part 19133140 (Transfer Cases). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

The stock here is genuine GM, and this Transfer Case keeps the original engineering number, which matters once a number has been superseded more than once.
