    On most cars with a 4 speed automatic, optimal RPM should be at 2,000 RPM plus or minus 200 RPM at 60 MPH. If you car hunts for the right gear or shifts roughly, you may just be low on ATF fluid. Check the level and add fluid if it is low. It should be cherry red in color and at the right level on the dipstick with the engine warm, running and in park position on level ground. If you haven't changed the fluid and filter in the last 2 years, you should do so now. Make sure you only use the recommended ATF fluid for your car. This is a cheap way to prolong the life of your transmission which is very expensive to repair.

    2200 rpms is close to max for normal conditions, Harsh shifts may be a sign of problems arising, check your fluid level, colr and smell of the trans fluid, also check for leaks around the bottom of trans.Leaks are the main cause of trans failure. Most tranny shops wont charge for a test drive, but please get more than one opinion. If you have to take it to a tranny shop do a little checking for instance the BBB Better Business etc etc.
