Automatic Transmission Case – GM (24276009)

Automatic Transmission 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 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 Case is listed as part 24276009 (Transmission Assemblies). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is genuine GM stock, supplied for the Case with the manufacturer number intact so the reference on the box matches the catalogue.
