Ok guys.....there is always someone looking for advise on an automatic
tranmission. Now I'm not going to say go with anyone. All I'm gonna do
is give you a breif run down of operation. Hopefully this clears up
some things.
Take a vehicle with an open differential. Let's say one wheel is on
ice, and the other is on dry pavement. When you step on the
accelerator, the wheel on ice spins and the wheel on pavement does
little or nothing. This is the "equal torque" part of open
differentials at work. It takes very little torque to spin the wheel on
ice. So, the speed of the wheel on ice goes up, since it's not
providing much resistance.
I don't mean to go on and on here but maybe this will help to understand it a bit better.
Ok....
Normally our pumps have a physical governed limit of roughly 2500-2550
RPM. That is the max upper limit that the engine will turn over under
wide open throttle. This means that in "N" or "P" that with the
throttle pedal on the floor, the engine will rev to 2500 or so and
that's it, no matter how long you hold the pedal down, it won't climb
any higher.
