Tranny Fluid leaks when not used??? - PeachParts Mercedes-Benz Forum

I have a 1996 S420 with 46,000 miles.
Very Strange......
I bought this vehicle from South Flaorida in Feb. of this year.
I live in Minnesota (very cold, snowy, lots of road salt, just plain UGLY), so I didn't want to put this perfect condition vehicle on the road in the winter time, so I drove it off the transport truck and right in the garage.
After a few days, I noticed a small leak under the car. When I checked, it was tranny fluid. To the best of my ability, I thought it was coming from the pan, so I tightened the bolts. It still leaked, so I thought I'd wait until it got warmer befor I tackeled it.
As it got warmer the leak stopped. I thought it ran out of fluid. I tried to check it, (but it seams on a $91,000 vehicle in 1996), you don't get a dip stick.
I bought a stick and checked the level and it was fine.
I drove the car all summer with no issues, now it's cold again (20's-30's) in Minnesota and....son-of-a-gun if it's not starting to leak again?????

Is there an overflow? Why only when it's COLD????

.....Any Ideas????

Thanks!
