Need Help With Bad Engine Or Transmission Behavior
Drove down from outside of Philadelphia to Atlantic City this afternoon. After behaving beautifully for a little while, I started to notice what seemed like a transmission slip, mostly at low speeds. It got worse over about 25 miles, disappeared, and than returned intermittently. We got to Atlantic City and pulled into a parking garage. When using reverse, the car began to buck in a fairly scary manner. For the last couple hundred feet it bucked in drive, but less horribly. Parked the car and restarted it just in case - it bucked in park like it had in reverse.
Thoughts?

Thanks! I will pull the codes tomorrow morning.
One more bit of information - no check engine light. I know that doesn't necessarily mean anything ...

We got up this morning, checked out of the hotel, and went back to the parking garage. I pulled the codes, but there were no current (non H) codes. Started the car up: bad bucking and stalled a couple of times in idle, though she would move in drive. We parked the car and I told Ivelis (my wife) that I was going to perform a visual inspection of the engine compartment.
I poked around for a minute and than - paydirt. We have a fancy, heavy, and reasonably effective Blackwing air filter. The clamp following the MAF had come almost completely detached over the previous 75 miles, allowing a stream of hot and uncontrolled air into an engine that was believing what the MAF was telling it. I grabbed my geek Swiss Army knife and realigned and re-tightened the clamp. Ivelis restarted the engine and suddenly Grace was back to being her usual wonderful self.
