acura tl sportshift question

Good question. I think it depends on the model year and/or programming of the sport shifter. Some are designed to limit rpm's, or maybe even shut down the engine in extreme cases.

On the 2000 TL, the car will shift through 1 into 2 and stay there if you put it into sport shift mode and don't ever shift. It will not upshift from

1. It will stay in 2 all the way to the redline and the RPM limiter will prevent it from going beyond that. Whenever you stop, it downshifts back to

3. Highway speeds in 2 will not run it up to the redline, though it will come pretty close. I'll bet you got really crappy mileage on that tank...

Thanks for the response. I did not notice the mileage being especially crappy but did not pay attention when filling up afterwards. More importantly, did that do any harm to the engine running with such high revs for so long?

Probably no damage. The engine keeps itself in its normal operating range (i.e. below redline), The transmission is not doing any shifting, so there should be no undo wear on the clutches etc.

If 2nd gear was not previously well broken in, it is now. Did you have the recall done that added the oil jet to cool 2nd gear?

About 140 miles, 120 of which were at highway speeds.

Yes I did a while back. Interestingly, the car went in to the dealer for a scheduled 60,000+ mile check up at the end of that trip. Nothing out of the ordinary showed up in their tests, but extra wear and tear won't show up in the diagnostics I'm sure.

Does engine power level off when rpm hits red line? Obviously it did not shut down.

miles in >2nd gear? Ouch! How could anyone drive long in 2nd gear with the engine screaming >and NOT think that something was wrong?

OK, new piece of information after talking to the driver. Somewhere between 60 and 70 mph, the display "2" flashed and it changed to "3" by itself - again, without upshifting while in sportshift mode. Could the leveling off before redline have caused this automatic upshift?

- Still puzzled, but a little less so.

One would then think that unless the music system were playing at full volume, the extreme engine revs would be heard.

I'm pretty sure mine won't do that, though I really haven't held it at redline for any length of time to make that test.. Maybe she bumped the shifter?

Its not as hard to do this as you might think. The car is really pretty quiet with the engine running at high RPM.

I have accidentally done it myself a couple times in the 5 years I've had the car. All it takes is some traffic disruption that forces it to downshift, coupled with a distraction of some sort that causes you to forget it was in sport shift mode and off you go in second. What has jogged me to look at it both times was the unexpectedly strong engine braking when you let up on it. There was not enough noise to get my attention with the windows up and the radio off.

I think I used to do that a few times myself before I lost interest in using the Sportshift.

Who said she was a "she"? LOL. Actually, the striking clue was the flashing "2" before it changed to "3" so I doubt that the shifter was bumped. Methinks some logic in the engine computer "burped" to relieve the condition.
