[pompous]

My transmission had been slipping (occasionally) over about the last month. I don't drive the car all that much.

Today, it wouldn't shift into 5th gear. I stopped at a stoplight and it wouldn't go past 3rd. I parked the car for an hour or so before making the 2 mile commute back home and it shifted fine, except for one time it didn't want to go into 5th again. I put it into "manual mode" and shifted it up and down and all through the gears jus to see if it'd work. After that, it was fine again. It has about 100k on it and never a transmission fluid change. Although, it was my impression these transmissions were supposed to be maintenance free. Either way, I'm looking at changing the fluid tomorrow (maybe).

Any thoughts? Am I wasting my time changing the fluid? Is the tranny pretty much gone?
