If the rest of the Transmission continues to function, then result is that the engine RPM's will be higher when cruising than is normal. Overdrive reduces the RPM's at the speed where it engages.
It changes the ratio between the engine rpm and the drive wheel(s) rpm.
this means that the clutch plate is slipping, you should also notice a funny smell from under the bonnett
It is normal for the RPM to increase a little when put in park or neutral. If the RPM increases by a lot, then you need to adjust your idle speed.
You can also relate this to the car crank shaft speed , and it is measured in Revolutions Per minute =RPM's. faster your crank shaft rotates (RPM's), the faster your pistons travel up and down the cylinders, thus the faster your car will go. Hope this was what you were looking for...
Gearing down increases the engine's revolutions per minute (RPM) and torque, but decreases the speed of the car. This allows the engine to work at a more efficient RPM range for the desired speed or acceleration.
A typical idle speed for a normal car engine is 600 rpm to 1,000 rpm. It is higher for buses and motorcycles. RPM stands for revolutions per minute.
that car has a rev limiter to make ur tach go higher find and eliminate it
Check/replace the thermostat.
If you're talking engine rpm, cruising down the highway doing the 65 mph speed limit, an average rpm would probably be 2000 to 2200.
It is a tachometer, an instrument showing the speed of the engine in RPM (revolutions per minute).
Your tachometer is broken.
