What causes the RPM to not go down while driving?

When you step on the gas and reach a certain speed the transmission should automatically shift out of first gear and go into second gear. First gear causes the engine to rev higher but gives more torque at the wheels to help the car get going faster. Second gear allows the engine to not rev as high and makes the wheels spin faster but with less torque. The higher the gear the less torque you get at the wheels but the engine does not rev as high. Even though the transmission is not shifting into a high enough gear do not guess that the transmission is the problem because many times the engine is not putting out enough power for the transmission to shift properly. The only way to tell is to put it in neutral and floor it. If the RPMs do not go nearly to the max on the tachometer have the car tuned up fully and see if you still have problems. I hope this helps.

Why does your engine rev up while driving?

Thanks for your interest. Yes, when you rev car engine while driving keep your foot on the brake the time of revving it up, but remove it before dropping the shifter into gear if you want to slide around as you leave the area. Put it in neutral rev and back in gear, go as fast as you want. Here always need a practical performance. So be careful.

Check the engine for proper cylinder compression. If the pressure is low then a blown head gasket could be leaking and causing the problem.
