Gearbox Repairs & Replacement

Lack of Acceleration

Lack of acceleration or a slight delay in acceleration after changing gears is a common gearbox problem sign. At times while driving you will notice a slight delay in the acceleration of the car after shifting gears. A delay of less than second can occur in manual transmissions but this should be only occasional to be deemed not a problem.

If you have a problem this type of delay will be longer and often more frequent with automatic transmissions. If this occurs where your RPM increases after shifting gear but the cars speed hardly increases, this will be a problem that is worth looking at.

Cars Gears Slipping

When changing gear, this should be an easy action and when you have found gear it should stay in it.

However you have a problem if you shift into gear, put pressure on the acceleration pedal and the car jerks and falls back into the previous gear. This is a common problem of the gear slipping.

The Cause and The Repair

You do not want gears slipping because they will harm the gearbox and can also put you in a dangerous situations.

A damaged shift work is often the reason for gears slipping. If the gear for is damaged it does not move properly to lock on to the correct gear which causes the transmission to automatically drop back. If it isn’t this, our mechanic will look if the gear teeth are worn, failing that it could be due to low transmission fluid.

Car Shaking with a Grinding Noise During Gear Shifting

If your car shakes or grinds while driving then the car has a problem.
If you have a grinding noise during changing gear and the car shakes then you have one of the common of gearbox problems.

The Cause and The Repair

If when checking the grinding occurs after fully pressing the clutch pedal it is very likely this is due to worn out clutch plates.

If it happens after you have taken your foot off the clutch pedal, the issue is more likely to be with the gear synchronizers. In either case the parts will have to be replaced quickly because the more grinding that happens the more the damage will occur to your gearbox.

Fluid Found Under Your Car

There are different fluids within the cars engine mainly for lubricating.

If you find liquid under your parked car, there is a good chance it is transmission fluid. It is easy to check because gearbox fluid is a bright orange colour.

The Cause and The Repair

If its bright orange and you suspect its gearbox or transmission fluid, it is vital you find the leak and top up immediately. Transmission fluid should always be at an ideal level for proper lubrication. If it isn't it can cause severe damage to the fast rotating components of the transmission.

When trying to locate the leak start with looking if there is a damaged fluid pan or a broken seal. If this leak is found quickly then often just this part will need replacing without any other damage. HOWEVER IF THIS IS LEFT the gearbox components could incur damage which could lead to a hefty bill for replacement.

Car Gear Stick is Stuck

You may find at sometime the gearstick is stuck and will not move. In the case of automatic gearbox it will probably get stuck in one gear and will not budge even when trying to give it power through the accelerator.

The Cause and The Repair

Normally if a gear stick cannot move this is due to a dysfunctional clutch linkage. If the linkage is damaged or the clutch is simply worn out due to use, the load won’t shift and the gear will not slot properly.

If the same problem occurs in an automatic gearbox car it is normally due to a failure in its electronic system. This is because its the electronic system thats responsible for the gear shifting timing is not making the gear shifts work correctly.
