80mph hickup
usually my TL-S hickups at 40-50mph while driving on local roads.
Today it produced a hickup at 80mph. That did not feel good.
It did it after I went over the top of a mild hill (overpass actually)

Does "hickup" mean when it feels like the car very very quickly downshifts and upshifts.....a quick jolt and then the car acts like nothing ever happened?
I had that very often on my first tranny, but still get it occasionally on my new tranny....always at highway speeds.

The hickup feels like quick downshift/quick upshift. It also feels like loss of engine power.
A few times I was able to see the tach during the hickup - the RPMs go down about 500rpm and then up again.
It usually happens to me when driving 45-50mph in a steady manner with light, steady pressure on the gas pedal (or on cruise control). It never happened on the highway until yesterday.
It feels pretty uncomfortable - it catches you off guard, slightly propels you into the dashboard, feels and sounds like the engine is going to quit.
Some people say it is caused by torque converter locking/unlocking, some people say it is caused by grade-logic in the tranny. All I know is that I have never experienced this in any other car.

Well, you already mentioned it... but it really does sound like the Torque converter locking/unlocking. Whether or not it's b/c of grade logic is really irrelivant. The TC in this car is more noticable then others... which is why you're feeling it.
Once I started feeling this happen I learned how to control it. Now I can pretty much fully control when the TC locks or unlocks by slightly varying pressure on the gas pedal. I use SS all the time... so that may make it easier too since I always know what gear I'm in.....
