I know what you guys/gals will say. You just though of it after almost 10yr. But I do like to get a serious discussion.

How should you down shift on a Ml320 tiptornic. I usually feel I need to down shift when going up hill and feel I don't have enough power (I am sure many of you want to down shift on flat ground when you feel you don't have enought power too).

The questions is what should you do about the gas peddle. Of course you could do just about anything with the gas and the transmission is smart enought to take care of itself. But the questions is what is the most optimal for power and wear on the tranny. So here is the options.

1. keep the gas peddle the same and just shift.
2. Rev the engin when you shift. A sub questions to this is when and how much to rev. Do you rev just right before, during or right after? Or do you try to do the same as if it was a manual, rev while you shift? Same questions about how much to rev do you try to do the same as what you would do on manual (rev to try to match gears).
3. Let your foot off the gas and then shift. My think behind this is that less power (gas) being apply to the gears would reduces the changes of causing damage (may be a stupid theory). This is what I have been doing like I said it may be a stupit theory.

If am sure many of you many think of other options too...

thanks
