Anyone that has a Camaro rear differential and is doing some road racing or AutoX might be interested in the Z/28 rear cover.
GM added a cooler to the Z/28 diff much like the ZL1 except they built it into the rear cover instead of the case. This make it pretty easy to add a cooler to your car.
On the Z/28 GM uses the TR6060's fluid pump to pump the transmission fluid from the transmission up to the radiator then back to the differential then to the transmission. If you were to do this on a G8 you would most likely need to switch to all AN lines or just add a separate fluid pump and radiator like I've seen done before by another member.
22923280 is the GM part number for the cover.
