wow, tons of responses, thanks guys...


for those who say it's not good to occaisonally shift an automatic, why is there lower gears then? what is the purpose of having a "L"? i mean why would you need to ever put the car in first gear?

also, i found a TON of articles online that say that with the newer cars, they build the trannys so that they can handle the stress of changing gears... so now i'm in the same boat as i was... some people saying it's ok, some people saying it's not... does anyone have a definitive answer that's based on fact, not an opinion?

thx

If it were supposed to happen, it would have 1234.

IMO, let the car do and run within the design limits that it was intended for, if it wants to shift let it. The only thing I can see that would be usefull is if you are about to pass someone and want to downshift for that extra time and speed. Basically, in that senario, you probably should not be passing either.

First of all I don't really know much about the strength of the automatic transmission but I also up and down shift it ocasionally.

Now my question is:
If it is bad to downshift an auto why does it say in the owners manual that you can downshift while going down or up hills.

you can do it, and doing it in NORMAL driving occasionally shouldn't do anything bad to it. performing constant full throttle upshifts and downshifting at high rpms/or multiple gears would introduce a much greater shock though, and typically higher shock loadings do more damage.

I gotta tell you guys I went to Moroso last week and tried shifting from L to D at redline and my time was a full 4 tenths slower then my own little powere launching technique. THe only problem was I didnt shift into Intermediate (I) I went straight to D at redline. I ran 17.1 @ 80mph with that run and when I launched it my own way my best has been 16.7 @ 81mph. I hate traction control and thats wat sucks about the auto, especially when drag racing.

Steep Downgrades. Steeper than you'll probably ever see in your lifetime. hehe. It's to keep the car from racing out of control and to keep you from burning up your breaks on a long steep downgrade.

I'm no expert but I'll say you're going to put more wear on the tranny than if you leave it in Drive. That's really just common sense talking though. The harder you drive it, the more wear it's going to take.

GM's literature about the Hydramatics for 2005

IPT does in fact make a manual shift unit for the car. In fact, is it switchable between normal drive and manual drive. The two things I don't like about it are 1) its kindda ugly, just a plain metal box with some buttons on it, 2) its one of those devices that gives you the power to really break the transmission if you push the wrong gear button at the wrong time.
actually there are solenoids, they are triggered by your PCM. i didnt take the time to read that link but im sure its hidden in there somewhere.
