    have a 2003 GT, about 130K miles on it, got it back in October and its been running great. Took it on a road trip from Seattle to San Fran and back. Drove through some mountains, but didn't push anything hard or notice any weird behavior. been back for 2 days and now i'm noticing some weirness in the shifting and power, primarily in 3rd. going from 2nd to 3rd, it doesn't shift until about 4K/30MPH, then I seem to lose power and acceleration until about 40-50, where it revs up, then shifts down to just under 3k, seems to stick for half a second, then shifts to under 2k (where i'd expect). this only really happens (or gets noticed) when going up hill. Tranny fluid is full and looks clean, but its due for an oil change after the trip. Any ideas what the issue could be? I'd just like to be a little more informed before I take it to the shop.

    Just a quick addition: took it for another drive and it seems to lose power anytime I go uphill, no matter what speed I'm at......
