Help me identify this leak
I'm thinking transmission. The only significant amount is the drop in the pic above. That hose is right under the radiator. It goes into the radiator, and goes back toward the engine/transmission area. Got work clothes on, haven't been able to crawl under yet. I'm on the road today too.

Has anyone else had experience with this?
I noticed a similar leak on mine and am still under warranty. I made an appointment at dealership for next week, hoping they take it serious and fix it.
