Overheating has been listed as one of the most prevalent problems that occur with the Mini Cooper gearbox. When you begin to experience this overheating problem in your vehicle, you’ll require the assistance of specialists to repair or replace the gearbox.

However, aside from overheating, there are numerous other issues that might arise with your transmission or gearbox. As a Mini brand car owner, you have to be conscious of the many gearbox faults that may arise in your vehicle so that you can know what to do when you experience such problems. Here we will discuss some of the issues that you may experience with your Mini gearbox and how you can fix these issues.

How To Know Your Gearbox Needs Repairs

Crunching Noise When In Neutral

A crunching noise may be heard whenever the engine starts running, even as the Mini is in neutral. If you are experiencing this, it means your gearbox is malfunctioning, and the transmission is not correctly aligned with your engine, so even if your car is in neutral, the shaft connecting the flywheel toward the gearbox will jam and generate the noise.

Noisy Gear

You may notice some noises coming from the gears when your back wheels are spinning. These sorts of noises occur due to several reasons, ranging from dryness on the rear bearing on your main shaft to damaging effects of the drive gears. In this case, the noise can be detected in neutral and can be quite loud. If this noise appears in your clutch and at the rear of your Mini, it might be coming out from your gearbox.

A Humming Sound When Your Vehicle Is In Neutral

When the transmission in your Mini is not operating correctly, you may encounter a humming sound. This can happen because; There isn’t enough lubricant in your Mini, or the shaft has become worn out. Another reason that can make you hear a humming sound is when there is excessive backlash throughout the gear train. Also, if the gear gets burnt, chipped, or is poorly manufactured or mismatched. Finally, the shifting forks may begin to rub in grooves, causing the gear to interfere with your driving.

Shifting Becomes Hard

The gearbox can occasionally produce shifting troubles. This might be risky when driving as you are unable to move any of your gears. Gear shifting may become hard if the primary shaft’s splines are deformed. You can also experience this problem when the clutch setting in the transmission is not properly aligned or you have battered gear teeth.

When any of these issues arise, shifting on your Mini will become difficult and may become stuck. To get your gearbox fixed, you’ll need to see a professional technician.

Oil Leaks

When your gearbox fails to function properly, it might cause items to shift and allow oil to spill out. Oil leaks from the gearbox can occur as a result of an excessively high level of oil. Another reason for an oil leak is when the oil gaskets or seals are broken or improperly placed or your cover bolts are unsecured. This may also occur if the case or cover has a crack in it.

Gear slipping

One obvious issue with your Mini Gearbox is its ability to slip itself out of gear. If this happens while driving on the highway, it might become a perilous situation. These are some reasons why your gearbox might fall out of gear:

• The mesh’s teeth become worn
• The lock spring of the shifter breaks or weakens
• The control mechanism malfunctions
• Inappropriate alignment of the gearbox with the engine

If you have experienced any of the above problems with the transmission or gearbox in your Mini, it is critical that you consult a professional technician as quickly as possible to get the problem resolved.
