I think I figured this out! When cruising at a steady 50mph it will only downshift to 3rd! Today as I was accelerating to 50mph I stomped it and sure enough here comes 2nd! WOW :eek: what a difference! Felt like the car was coming out from under me! As for the manual issue, I had a certain budget and was looking for a certain car and this fit the bill, I did want manual but it was not a priority. Shifting in NYC is not the most fun one can have Also makes the wife happy she WAS able to drive it :D
These cars will not always drop down the same number of gears at a given speed. It is really irritating and can be very embarassing. I thought something was wrong with my car. I once asked C4C5Specialist about this very issue. He told me that due to all the various parameters involved in the computer's decision process, this is normal. I will bet you that if you had tried it again right after it didn't drop down as far as you thought it should, that it would have gone, and , if not that time certainly the time after. Lord, you shouldn't have to do it two or three times to get the full kickdown. My major points of irritation are 30-35 and 70-75. It shouldn't be like that!

Can anyone say for sure that the Powerloader takes care of this issue? Boy, that would sure be nice. Thanks!

You may have missed the thread I started about 3 weeks ago on this same topic...The answer is that the delay is NOT from the kickdown but from the "fly by wire throttle blade response; that the signal to the TB has to still open mechanically and hence the delay...some people say that the power loader has helped while others say no...you can look at the reponse by h rocks on 8/13/01 or look at the LONG thread and comments titled "FLY by WIRE throttle blade response ...causes hesitation" (dogdoc) (archives)which is me...hope this helps.

Max, thanks for the reference. However, the issue I have is not with the delay, but the fact that the transmission won't always kick down as far as other times from the same speed. Sometimes it drops down one gear, sometimes two. My two areas of concern are 30-35 mph and 70-75 mph. I was wondering if the Powerloader would take care of that problem. Thanks!

Thanks for the ref; I had missed that thread somehow. The lag is definitely an A4 thing and I really do believe it's the trans. The PL does not fix that lag, although the PL makes the shift points aggressive enough that you might psychologically overlook it.
I'm as picky as hell and even with the PLII still feel that split second lag. The difference is that once it catches, the car starts flying and the shift-points are more aggressive.
The downshift thing, I had always assumed, was the stock PCM code doing too much "thinking" when trying to determine your driving characterstics. I think the learning PCM is kind of misplaced in a car like the Vette, to be honest. Im guessing that the stock PCM program will lean towards less agressive downshifts for efficiency.
Since getting the PL, the downshifts feel very aggressive. The best example I can give is this:
In this urban 5h;thole I call home (NYC), stop and go (mainly stop) traffic is really the norm. What happens to you 99.9% of the time is you start moving quick enough to get out of first, and then within seconds, have to ease off the gas due to traffic... Generally, when you hit it again, you will still be in 2nd and will probably wind up making the day of some fart-pipe Civic that "burns you".
The only alternative to that problem, pre-PL, was to really gun it to force the downshift at which point you are laying down MUCH too much throttle for the city streets and wind up looking like an @55.
With the PL, the PCM seems sort of psychic... In the scenario I described above, I now get a crisp downshift immediately without having to punch it and I can finally take those damn Civics (at least to the next light :D )
Any A4 guys who are considering the PL and are in NYC, look me up anytime and Ill take you out... I've got ProFlow+, Borla cat-backs, the PLII and 2.73's, so the car is still somewhat stock. Ported throttle body, crossover pipe, and Z51 sways/shocks *are* going in next week though :D
Hahaha... edits are my attempt at dealing with this fascist profanity filter!
