overdrive switch ?

[mitsuclipsegsx]

is it ok to switch the botton while driving like say i was going uphill and i hit od off then once i got up hill turn it back on i heard its not good to keep hitting the botton on and off true or false?

Well, every time you do it, it's a shift, so if you just keep going back and forth, back and forth, you're going to wear shit out. Every day on my way to work, I shift it out of OD at the bottom of a large hill, when there's no load on the tranny, instead of waiting for it to downshift itself when I'm halfway up the hill and there's a load on it.

its a automatic transmission. hence the word automatic .... it shifts itself accordingly when it needs to You really don’t want to mess with the switch .. Electronically controlled automatic transmissions are very bad news. It’s an electronically controlled switch that controls something the trans does. The more you push it, the more you wear it out, and the grater the chance it can fail. Look around you will see people talking about when they push it sometimes their trans does something funny. The ONLY reason to hit the button is if your racing from a fast roll, from whatever the speed is at, at about 4,000 rpm at the top of third gear, so now when you both gas it the car does not have to down shift, and your right on the edge of boost. That’s the only time you need to touch it

Just becuase the transmission shifts itself doesn't mean that the point at which it shifts is the easiest on the trans. Since I know the trans will be shifting at some point on the hill if I maintain 70 MPH, I press the button to shift it while the trans has almost no load on it, thereby reducing wear.

It's kind of like why you should double clutch a downshift on a manual, sure, it may not grind now, but if you reduce the wear on it, then it will be longer before the parts wear out.

(and I also only use drive if I'm in town and will be consistently going 30 MPH, so the trans doesn't have to downshift every time I decide to pick it up a little, but that's just a quirk I picked up from my Crown Vic, since the AOD bogs at 30 MPH)

i dont know man i think your being a little to anal about it, its a automatic. put it in drive, and drive. its not made to be drove like a stick. when the car decides to shift, its going to shift at the right, perfect time. I think the engineers are a little smarter then you. They are not going to program the car not to shift at high stress points. What YOU think is hard on the transmission is more then likely not.
