Q5 3.0T APR CPS?, ZF transmission cooler?

Hi All, hopefully this doesn’t get buried too quickly and the vast knowledge base of AR can help out.

Can someone please explain to me how the engine/SC and ZF (8 Speed) transmission coolant systems are tied together? I’m seeing some reports that the factory transmission cooling is tied to the engine coolant loop but I haven’t been able to confirm that. If I was to make the APR CPS work on the Q5 would the engine and transmission both beit from the additional cooling?

Does the APR CPS work on the Q5? I’ve seen threads about people using it but APR doesn’t seem to list it on their site as available for the Q5 3.0T.

Thanks for your help
