My car is doing a thing (and I would like it to stop)

My car is doing something kind of alarming, intermittently. I'd love to get some guesses as to whether I need to see a transmission specialist or not before I take it somewhere.

(I have brought it to a transmission guy before, but it of course didn't happen while he was looking.) So what's happening is periodically, while accelerating, the car will slow down sharply, in a jerky fashion. The jerking stops the instant I take my foot off the gas, and usually doesn't come back immediately. The RPMs don't seem to change much while this is happening. It's been going on for probably a year or so, but has gotten more frequent in the last couple of months. The Check Engine light does not come on, and when I brought it in last winter to the transmission guy, he said there were no codes to pull. At that time he changed the transmission fluid and the spark plugs since it was time for it anyway. This didn't change the behavior at all. The only other unusual thing about the car is that occasionally it goes into a fast idle while parked - it's done this since I got it. (The car also seems to have less acceleration these days, but it's a four-cylinder sedan and was never particularly zippy, so I can't swear it's not just me.)
The car is a '01 Saturn SL1, automatic, with about 105k miles on it. It's generally been a good car - no real problems until now - but I am not afraid to take him out back and shoot him if this ends up being a major problem. I would rather not spend a ton of money trying to diagnose it (although I will definitely at least give it one more shot.) Anyone seen this before? Any particular tests or resources I should look in to? And does it look transmission-y? (My usual mechanic, whom I like but I am not too attached to, doesn't do major transmission repair.)
