High RPM, doesn't shift into next gear

[Crazy K]

...when I am able to pull forward into my driveway, I move my gear selector from park to drive, shouldn't the transmission being in drive prevent the vehicle from rolling backwards? This is just at idle, not talking about anything over 900 rpm here.

 

no, it would not. need I elaborate? the hill is steep enough to overcome the idling car in drive. It will probably do the same when the car is warm if you did the same thing.

 

 

Can someone elaborate on weaken tranny pump details? it may be a problem one of my cars has. my 91 vert won't go unless pushed in gear or lifted, operated in gear while in the air, and then dropped... It can even be off when dropped, it's just the very first time you try to move the car cold.

so your saying that if your in drive and on a hill with the nose faceing up it will roll backwards if you let off the brake?

 

if thats what your asking then, its perfectly normal for it to do that. mine does.

Alright, thats what I assumed. Just seemed wierd that in my mom's '97 Avalon, her vehicle doesn't roll backwards.

It depends on how steep the hill is, it shouldn't roll back if it isn't that steep, it should stay still. If it is really steep then it will roll back.
