Why do my RPMs go up but car doesn't accelerate?

What causes RPMs to run high while driving?
Faulty speed sensor
Automatic vehicles use speed sensors to determine when the gear should be shifted up or down. In the event that a speed sensor doesn't work correctly, your car might not shift gears when it needs to. This can cause high RPM as the engine has to work harder.
Can high rpm damage transmission?
Excessive High RPM
While extremely low rpm and high loads will damage your transmission right away, sustained high rpm may damage it over the long run. High rpm means more wear on the bearings and oil seals, and quicker transmission fluid breakdown.
Why are my RPMs going up?
Hi There, It sounds like you may have a dirty or failing idle air control valve causing your engine idle to fluctuate. The idle air control valve is a small valve on the engine's intake system that reads the air intake as it comes into the motor.

What happens if your RPMs are too high?
Typically, engines idle at about 600-800 rpm. Older engines may go up to 1200 rpm or more while warming up. But if the engine is revving up while idling, even after it's sufficiently warmed up, you might have a problem. High idle speeds waste fuel, cause extra wear and tear on your engine, and can be unsafe as well.

Is it bad to shift at 5000 rpm?
If you drive at 5,000 RPM, that bearing is going to use up its lifetime twice as fast as if you were driving at 2,500 RPM. On the other hand, "lugging" an engine at too low an RPM can be harmful, as well. If your prime directive is mechanical lifetime, shoot for lower RPM within a reasonable range (i.e. not lugging).
