So the truck has been parked for a few days in the driveway with E-Brake on. Battery is out so has not been started or shifted. All was fine until this morning. I came outside and there are a couple of puddles of ATF under the truck (one large, one smaller). Any idea what would cause that?

Maybe it was borderline over-filled when you parked it and fluid drained back from a cooler or the torque converter and pushed some out of the vent tube on top of the trans? Just a guess, someone feel free to correct me if this isn't possible.

Have you crawled under and looked to see if you can tell where it came from?

I guess that would be best case scenario. I will get under there and take a look.

Looks like a crime scene. You have trans fluid dripping off of wherever the original leak sprayed it.
It just took awhile for it all to run down.
Was the outside air temp pretty cold when you parked it?
Did you get a really extreme change in temp?
Or was it all normal?

I'm in Florida. The temps have ranged from 70 to 90 since parked last week.

A couple pretty common leak points when parked are where the dipstick tube enters the case and the pan gasket, there are other possibilities though. You are definitely going to have to climb under there to determine the source.

Time to crawl under it and find the leak..
If its too dirty to track it down, clean the holy crap out of it.
get it as spotless clean as you can.
Keep the trans topped up and take it for a drive
Then look for the leak.
If you still cant track it down,
Go old school, like 1930s old school
get a chalk bag or some fine flour and powder the likely suspects with it.
It will show up pretty fast and it all cleans off with water

This is no help, but I love an ATF party in my back country property. Now this being a GMT 400 forum, I do not think there are any Canadian Liberal Green Energy Wack Nutters to report me to the RCMP. ( I love my Canada, and the US) No better place to be on planet earth.
