Transmission fluid mess

[Condition1]

Good day all, I have a transmission issue I’m hoping someone can give some insight on. I was pulling a small lawn trailer all day Friday. I’ve pulled it many times before. While unhooking at the end of the day I see a thin coat of oil all over the trailer tongue. I look under the truck and all the underside is coated. Further looks tells me it’s tranny fluid. I park the truck all weekend with cardboard under it. Today is Sunday. I have a few spots where excess has dripped off the frame. But no leaked coming from the tranny itself. No dash lights either. Any ideas? Could it have overheated and spilled out of a vent? Is there a vent? As a side note I took the truck for an oil change at a major retailer in June. The idiots drained tge tranny instead of motor oil. Could they have overfilled and an overheat made it spill over. Thank you for any thoughts.

Over filled and puked from dipstick/filler (if you have one). Overheated and one of your seals leaked. Leaky seal on the verge of letting go entirely. You need to get it up on a rack and find the source. If you aren't comfortable with trannys take it to a tranny shop, not the dealer unless it's still under warranty. The dealer techs are parts changers who only do what the OBD tells them to do. Some info on the vehicle would help, year, engine, tranny, etc.

seems a lot easier than pulling up a dipstick when the engine is at temp. (insert eye roll emoji).

i think first i'd check if they forgot to put the overflow plug back in. maybe once you got up past the checking temp it just started flowing out.

It's also possible you ran through a puddle of someone else's tranny fluid. IS there any in front of the tranny?

No that’s what I was hoping. But it the oil starts in front of the pan and back

Thanks for the reply. I’m taking it to the shop to check it out. I don’t trust shops but I don’t have a choice in this circumstance.
