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.

What causes a cars rpm to suddenly jump while driving?
What can cause the RPM on a car to jump while driving is a problem with the transmission. It could be a problem with the gears in the transmission itself.
What causes lug while driving at low rpm but not hi rpm it does not do it with the vacuum hose disconnected from the egr valve.?
Many things can cause lag while driving at a low RPM but not at a high RPM even if it is not the vacuum hose disconnected from the EGR valve as it could be the fuel filter. It can also be the park plugs.
What causes RPM to go up and down while driving and you are not accelerating?
Most likely going down hill, the faster the wheels go, the higher the RPM will increase, for this to increase the vehicle either must be going downhill with no brakes applied or the throttle(acceleration) has been depressed.
Why does my 2000 dodge truck serges up and down at 2000 rpm while driving at normal speed on the highway?
Because it does and that's okay :D
Why did your RPM gauge stop working?
while driving the rpm gauge work perfect, when start accelerating the rpm can not exceed 3 with interruption in the engine
Rpm are high while driving in snow?
Loose belst Opp's that's belts
What is standard of rpm while driving?
depends on what car and what engine, typically if your cruising on a freeway, you will be running at half RPM or at the most 3/4, but the lower RPM the better with that you get better gas mileage.
What causes a 1996 Tracker manual transmission to barely go to 3000 rmp once in fifth gear with the throttle to the floor and after driving for a while go to 3500 rpm or 65 mph?
that sounds pretty normal to me
What are signs of transmission problems?
Gears slipping, such as sudden high RPM's and loss of power while driving. Failing to change gears at a certain RPM in an automatic.
Why does your 1992 lumina z34 stop revving at 3500 rpm?
while you are in park? That should be normal. While in gear or driving, no that isn't.
While driving your car revs excessively reaching 6-7x1000 rpm What is the problem?
transmission is slipping
What causes my 1987 Buick Park Avenue to vibrate?
Most commonly a vibration while driving is from a broken belt in one of the tires, but if it's vibrating while sitting still, it's usually from loose motor mounts and/ or a higher than necessary rpm
