What is a gearbox in a car?
The gearbox is the second stage in the transmission system, after the clutch. It is usually bolted to the rear of the engine, with the clutch between them. Modern cars with manual transmissions have four or five forward speeds and one reverse, as well as a neutral position.
How do you know if your gearbox is bad?
4 Signs That Your Gearbox is Failing Listen to your gearbox for any noises. Inside the gearbox is a rotating plate that can make any number of noises if dysfunctional. Can you smell burning? Clearly burning isn’t something that healthy gearboxes do. Failure to engage a gear. Your gearbox ‘feels’ different.
What is the main purpose of a gearbox?
The purpose of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the speed function. If the enclosed drive is a speed reducer (speed output is less than speed input), the torque output will increase; if the drive increases speed, the torque output will decrease.
Does an automatic transmission have a gearbox?
It may seem simple from the driver’s seat, but an auto gearbox is one of the most complex systems on your car. An automatic transmission seems pretty simple; after all, you just put it in Drive and go.
Can a gearbox be repaired?
If your gearbox is down, you need it up and running as quickly and efficiently as possible. Repairing an existing gearbox can be a quick and cost effective way of bringing your process availability back to 100%, compared with a replacement unit.

What causes a gearbox to fail?
Here are some of the most common forms of gearbox failure. The major cause is inadequate lubrication caused by under filling, incorrect specification, mixing or incompatibility, incorrect lubrication and intervals, deteriorated grease or oil, water contamination and particulate contamination.
How long should a gearbox last?
Without service and maintenance, some transmissions can fail in as little as 100,000 miles. If you drive around 10-15,000 miles a year, your transmission could be down for the count in seven years! With care and service, transmissions can last 300,000 miles or more.
What happens when gearbox goes?
Performance. When your transmission goes out, your car’s handling will be affected. You may experience vibrations, slippage (engine revs but vehicle does not accelerate as it should) or different shift patterns in your vehicle. The gear shift on your car will stop working when the transmission dies.
What is inside a gearbox?
So it’s clear — a gearbox is always a fully integrated mechanical component consisting of a series of mating gears contained in a housing with shafts and bearings (to support and resolve loads) and in many cases a flange for motor mounting.
Is reverse gear more powerful?
Reverse, as it generally is lower geared and produces higher torque. But it does not increase or decrease horsepower/kilowatts. That will stay constant. The engine is the only thing that can change the horsepower – not the gears.
What are the types of gearbox?
TYPES OF GEARBOX Manual Transmission. (a) Sliding Mesh Gearbox. (b) Constant Mesh Gearbox. (c) Synchromesh Gearbox. Epicyclic Gearbox. Automatic Transmission.
Why does my car jerk when shifting gears with an automatic transmission?
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
What causes an automatic transmission to slip?
Transmission bands can wear out and cause slipping. Transmission bands can become worn or broken, which will cause the transmission to slip. Bands are what link the gears in the automatic transmission together. To fix this problem, the defective bands should be replaced.
Does changing transmission fluid help shifting?
Moreover, some automatic transmissions have filters that should be cleaned or replaced when the fluid is changed. However, fresh fluid is not a cure for gears slipping, rough shifting or other mechanical problems, so don’t expect a fluid change to be a magic elixir.
