Manual shifting an automatic?

I have the 4.0 and automatic with 33/12.50's and 3.73 gears. The auto wants to shift around 2000 RPM's and this seems to be too low. My question is, is it alright to shift the auto like I would a manual? I usually run 1st until about 3500 then into 2nd to about the same and then into drive. With the bigger tires it tends to lug a bit. This method works well keeping the RPM's up and getting up to speed much quicker. Is this bad for the transmission? Is there a way to make the tranny shift at a higher RPM on it's own?
Thanks.

Shifting yourself shouldn't hurt your transmission and will make things easier on your engine.

I'm new here, just bought my TJ, but not exactly new to driving

Keep in mind the 4.0 is designed to run most efficiently at lower RPM's, Personally, I'd let it shift where it wants.

Only time I ever shift it manually is when I'm towing my boat and I'm at a light. If there is alot of traffic, I try not to bog everyone down. So I shift it manually to get it up to speed quicker. Otherwise I let the jeep do what it wants.

A stock 2000 4.0 makes 181 hp @ 4600 rpm. Takes some revs to make power.

You don't even need to push the button, No there won't be any grinding. Yes you can down shift the same way.
It's not "bad" just inefficient.




Learn the difference between torque and horsepower and look at the charts.

i manually shift mine when pulling out on the highway, i tend to have to jump in between large groups of cars, so i need the acceleration to be there.

as far as downshifting, it is not as good on the tranny to be doing that, i used to have a 99 mustang GT and the owners manual said not to down shift, but it is good to manually up shift.
