i have a 3 speed auto in my 98 cavi and i was wondering wat happens to it when u maually shift it. and how good the 3 speed is. cuase i have noticed some satey mechanisms in it like it acidentally went into park luckily i wasdoin like5 but the car coasted then locked but then my dog some how clicked it int reverse at like 10 and the motor just died but anyway how tuff are these trannys and how can the kias with the maualmatic and the new jeeps be able to shift it like a standard and i can? does it hurt it???
why do you need to manual shift your automatic?
shouldnt hurt anyone elses car but I think something bad will happen if you try it
ive done it before to my dads sable and a month later the tranny went on it, either coincidence or its very hard on the tranny. I just know that was the last time im going to do it. Ill still use my 1, 2, 3 gears on ocasion I just wont shift up or down while using those.

Manually upshifting the 3sp does not work because it will just wait until it wants to shift. Like if I move it from 1st to 2nd at say 5000 it will wait until 5750 or whatever to shift anyway, or thats my experiance. I have done manual 3-2 on occasion to aid in braking down hills, and it has not hurt it.
It's called an automatic for a reason. If you want to shift, buy a 5-speed. End of story.
sounds like that fool who ran a 15 with the yellow turbo cavy who missed 2nd cause he was manual shifting
Thats because hes a @!#$ moron. Anyone who owns a car with a stick especially for any length of time wont be @!#$ up their shifting once you get used to it. and if you are still screwing up you need go get yourself an auto because stick clearly isnt for you. (unless your just hammed outa your mind)

i have an auto with 150,000 miles on it, i know i am going to get hell for this, but i shift up and down daily, just buy a tranny temp guage cause when you do shift it you get increased pressure, which can help performance but with increased pressure comes increased heat, everytime you overheat your tranny fluid you half life it, i have a four speed and it shift about 5-10 mph away from the rev limiter, i hold first until about 38, second 72, third will burry it, and fourth is just for cruizing on the freeway, so up shifting like a manual will not do anything to the tranny, it just increases the pressure, as far as going into reverse it will kill the motor and is really hard on things, then slamming into park while rolling is hard on the parking pin and axles and motor mounts, the 3-speed will hold more power then the 4 speed or the manual trannsmission, i have seen manuals blow out easy, just keep that tranny cool and keep the dog away from that shifter

Sorry, I should have elaborated.... heat is what will kill an auto tranny - guaranteed. If you are nice to the transmission.... ie. change the fluid on a regular basis, including the filter so it's nice and clean.... get an auxiliary cooler to keep it cool.... get a temp gauge on it so you know how hot it is... etc... you won't have many problems. Of course, nothing guarantees that you won't kill it if you're abusing it, but that's the risk you take.
Personally, I've had three autos, only one of which I've swapped out to a 5 speed (because I wanted to pick my own gears!). With a cooler, regular fluid changes, and an Interceptor at 100% line pressure all the time... I had no problems. But I also put it in D and left it there.... there's no point in shifting an auto, you can't make it shift better. You might think you can, but sorry you're wrong
Holding the gears and bouncing off the limiters is dumb. Do it right, don't Mickey Mouse it.
I used to do it as I lived in a very hilly area and it helped but it has little performance advantage. If you want true compression braking you still have to manually lock up your TCC.

Yea, ummmm. I used to have a J-body...
actually mine will run quicker if i shift it
the trans shift several hundred rpm before redline , and if i shift it my self i get about .5 increase in my 1/4 times
my 00 doesnt have a trans cooler , i do have the shift plus , and live in weather that exceds 110 degrees
how ever i do recomend a trans temp gauge and trans cooler , and the shift plus
i hated the auto trans interceptor only becauese it never shifted the same twice unless you had it set to max
if you manual shift your tranny, you will have the POSIBILITY of "BREAKING" the "parking pole pin", if that bitch breaks, it WILL fall into the gears, and DESTROY ever single gear!
how do i know? cause it has happened to me, i'm on my 2nd tranny and on my way to my 3rd one, this time around, i'm swaping in a 4spd tranny and NO more manual shifting, thats what i'm building my parts car for (a 5spd)

Somehow I dont see anyone busting the parking pin unless they're throwing it into park, with the car moving. Since that's when it engages. I dont know about any of the J body cars, but I know on the W-body, if you just leave the shifter in 1, it will go to 2 on it's own when you get to the shift RPM for WOT. Leaving it in 2 however will make it hit rev limit. What I am sure of is the fact that if it's Electronic or Non, it's got some sort of system set up for operation at WOT that will make it shift probably somewheres around probably 5800RPM. An electronic trans. will be more accurate/consistant at doing so. So you need to simply put the accelerator to the floor and hold it there.
Leaving it in the low gears may get you a bit higher RPM before a shift. But remember that it's set with your stock engine in mind. And the powerband for such. So it's pretty well set to shift where it should be shifting at. Shifitng it yourself is going to slow you down for 1, and possibly 2 reasons. 1, you'll get out of your 'optimum' powerband and put less HP to the ground than you could in the next gear. 2, you run the risk of hitting rev limit, which is going to hurt your times more. In addition, you'll probably put more heat in the trans, and like Lenko mentioned.... that's not good for it.
Either way, when you shift it like that, the PCM will still go to torque management mode, and pull timing for the shift, so you're not going to benefit yourself there.

Thanks a lot, Mr. Nice Guy It was my first time drag racing after getting the car back together... now I know it was a dumb move. Live and learn. Next time, I'm just going to up the Line pressure and leave it in Drive.

I've done it with my 3spd when i owned my Sunbird, didnt really accomplish anything, and i believe it caused trans issues. like Lenko (sorry if i sound like an ass), but it is called an Auto for a reason. Our Auto trans's arent the style that can allow manual shifting (ie triptronic etc)..
