Same Exact Thing
Looks Like I have same dilema. Noticed ATF fluid in driveway after a fully loaded vacation drive of 300miles. Checked ATF and it was within range on dipstick. Drove back and forth to work of 12 miles parking in clean space looking for leaks...none over a weeks time. Decided it was OK. Started trip this weekend, noticed some hestitation at Drive to OD shift point and saw RPMs waver between 2000 and ~2200 as I Drove at 60MPH. Seemed like it was dropping out of OD every couple of minutes irregardless of load. Going thru small town got a large shutter starting from a Red Light, but car seemed to shift normally into OD as I entered Interstate. After about 5miles, the Transaxle warning light came on. Seemed like Tranny stayed in D and didn't allow shifting to OD as RPMS were 2300 or so at cruising speed. Stopped at Nearest dealer, and saw no fluid on dipstick. Tried putting fluid in, but it ended up on the floor. Put it on lift and saw leak at same spot as your picture.
Don't know what to do....leave at dealer(which is 150miles from home), take to AAMCO, or just call and donate it. It's been great car with 94,000 miles but I don't want to dump a ton of money into it. Please indicate your finding..... I did see a TSB about fluid leaks but can't find it.
I did have the A/C compressor just recently replaced....Any connection here?
