How high should a car's rpm go before it changes gear?

my car goes up to about 2000 rpm before it changes gear. its an 1998 Toyota Corolla/LE model. it switches gear after 2000 rpm. is it suppose to switch gears that early, Thats first gear only btw. or does the rpm increase on each gear?How high should a car's rpm go before it changes gear?
In an automatic like you are talking about if you were to floor it it should run to redline before switching gears. If it isn't then you need to have a dealer check it out. Shifts are controlled by the cars ECU (comuter brain) so there may be something that the car is reading as being wrong or needing attention and it is limiting the shift changes to lower RPMSHow high should a car's rpm go before it changes gear?
It depends on the type of motor. Your car should have a red line on the tacometer and the shift should occur somewhere in the lowere part of the red zone (or lower). You should avoid running the engine in the red zone for extended periods of time as this will increase the wear and tear on the engine.
A lot of it all depends on how hard you are driving the car. The harder you drive, the higher the R.P.M. when it shifts.
You control that by how hard you're accelerating.
It all depends on how hard you press on the accelerator.
My dad is a really slow driver and when we're first starting out that's about how many RPM's we get. If you barely touch the gas pedal it won't get that many RPM's because newer cars are supposed to be more efficient. Another possible factor- if you on a slight decline, it won't take nearly as much power to accelerate. I wouldn't worry, Toyotas are great.
the standard is usually around 3000 rpm for changing gears. Cars usually cruise around 2000.
Make it bounce off the redline!!! If you want it to change later, use the manual gear shifting... The 'L' (for Lower or 1st gear) and '2' (for 2nd gear).



The new toyotas also have shorter gears than most cars, so that should be right if your driving slow. Toyotas never break, so I don't think theres anything wrong with it.
depend in how fast u want 2 go . avoid red line .
most newer cars can go up to 5000 rpm without problem. usually the car shifts when it senses it can, either through vaccumm or electronics. the more you step into the gas the pedal, the higher rpm should go, unless there is a problem. if car shifts too soon always, then maybe a tranny shop should look at it. Typically 1st and 2nd gears have highest rpm because they are small gears getting you up to speed.



But lower RPM will give better gas mileage, trade off is speed and HP
