Anyone ever seen this before?

The truck as been sat on the drive for 2 weeks. Yesterday I noticed a pool of fresh transmission fluid under the truck. Couldn’t see exactly where it was coming from. Pulled the dip stick and the tube was full of fluid and it seems to have overflowed from there. Started it up and the level went down. I’ve had the truck over a year and never touched the transmission. Record show it was serviced before I bought it and was returned due to a leak. The conclusion was it had been over serviced.
My first thought was maybe water had got in there and was pushing the fluid out but we’ve had no rain for a couple of weeks.

Anyone ever seen this before?

A similar occurence happened to my 92 Classic Range Rover.
I have had no leaks before on the vehicle or since.
Topped it up after the "surge" of fluid and all has been well since.

Anyone else have an issue like this?
