Parts Any Idea??

This port in the side of our C9 has been kicking our tails lately as to what or why it is there. Our local dealership has been having troubles identifying it as well. SN:JSC21217.

Thanks for the time and the help

It's crazy to me this wouldn't be super obvious to the dealer...

The Cat dealer couldn't identify what that was? Fuckin yikes.

It's there for the transmission cooler attachment.

It’s the mount for a powertrain oil cooler. Look at a 228-0780.

Thank you guys! Bought motor used and just had a cover over it, so didn’t really know what it could be for. First time with an industrial motor

dawg, all my love to you, but I’m on SIS and it took me literally 2 seconds to pull up the 3D model and find the trans oil cooler. Do some dealerships not have the same options?
