Just last night i was driving, engine still cool, no problems though. i turn at a redlight, get giong about 25, tap the gas and suddenly there is a loud high pitched..whirrrrrrrr and

i was hardly accelerating at all. i let go of the gass...i turn of my music, tap it, whirrrrrrrrrrr,

i quickly feel the automatic clutch, its in drive, i pop on the light to confirm, not in neutral, not in third, in drive, i check the parking break, its fine, i tap the gas, whirrrrr

i start to pull over and tap it one more time and its smooth as butter, regular deep voice of automatic transmissions shifting gears. no problems the rest of the night.

I suppose what ever has caused my drastic decrease in mpg all the way down to 25 all highway driving at average 65mph is also causing this problem. Anybody have any ideas what is wrong before i head of to the shop on monday let me know.

I really couldn't tell you, the "whirrr" I assume is from the engine not the tranny? Since you said the car is still cool, it doesn't shift into the overdrive gear (4th) but once the engine warms up or gets to "normal" opperating temps it shift, that's if you have an automactic but otherwise I don't know, I'm just guessing. Hope its nothing too serious.
