How can coolant get into transmission fluid?!

[SPOW]

Just received my transmission fluid analysis back and surprised to hear they found a small amount of coolant in the fluid. This explains the poor shifting performance and quick deterioration of my transmission fluid. Can anyone suggest where these two fluids cross paths in the engine so I can replace? I see there is a transmission cooler, but I'm not sure if the fluids can mix there, if a seal was bad or a crack. 2018 CX5 2.5. Thanks for any help

There is a transmission oil cooler that is cooled by passing coolant through it. Probably the only place they intersect.

How many miles does your CX-5 have..? Those usually don't fail much unless they have many miles.
