You may know that every running vehicle depends on a functioning transmission. But do you know what a transmission actually does? One simple answer to this question is that your transmission protects your engine from redlining and failing.
All car engines have a maximum number of RPMs and reaching that maximum puts strain on your engine that can cause serious damage. A transmission shifts your engine’s gears to allow it to reach a greater maximum RPM that allows your vehicle to accelerate.
Not only does shifting gears allow you to accelerate, but it also allows you to control deceleration. This is why properly shifting gears is crucial to a smooth and safe drive.
It is important to remember to shift before your vehicle redlines to protect your engine from unnecessary wear and tear. This can be accomplished by keeping a close eye on your RPM meter located on your vehicle’s dashboard. When the dial on your meter crosses into the red portion of the meter, your engine is revving too high. While redlining, you will also notice physical signs of stress on your vehicle such as shaking and strange noises.
When this happens, you should immediately let off the accelerator to reduce the number of RPMs and strain on your engine. While the occasional brief redline may be relatively harmless, repeated redlining for extended periods will lead to substantial and expensive engine damage.
