2017 Yukon SLE Transmission Oil Line Size

Can anyone tell me definitively what size (diameter) the transmission lines are for a 2017 Yukon SLE? I have no way to measure them and need to make sure the cooler I plan to buy will have sufficient fluid flow. Thanks.

Kick starting this again to see if anyone can point me in the right direction. The camping season will be starting soon so need to buy the new transmission cooler in the next few weeks. Thanks.
