Gearbox Repair | Gearbox Specialist

Gearbox issues don’t usually start dramatically. In many cases, they appear as small changes in driving feel that are easy to overlook at first. These changes can indicate gearbox problems, but they don’t automatically mean the gearbox is faulty.

You might notice things like:

• Gear changes feel different: selecting gears takes more effort or doesn’t feel as smooth as before
• Sounds you didn’t hear before: humming, whining or rattling gearbox noise while driving
• Loss of smooth drive: power delivery feels uneven or hesitant, sometimes linked to gearbox slipping
• Gear selection issues: the car won’t go into gear straight away or needs repeated attempts
• Oil traces: marks under the vehicle that could suggest a gearbox oil leak
• General driveability changes: the car feels less responsive, especially in traffic or at low speeds

These signs could be related to the gearbox, but they can also come from other components such as the clutch or transmission system.

The only way to know for sure is a professional check. A nearby Bosch Car Service can assess whether the symptoms are caused by the gearbox and advise on the right solution — from a simple check to targeted gearbox repair if needed.

If your car won’t go into gear, it’s often noticed suddenly — usually when pulling away, selecting reverse or shifting in traffic. This situation can be frustrating, but it doesn’t automatically mean a major fault.

Possible reasons you might experience this include:

• Gear engagement feels blocked: the gear lever won’t move smoothly into position
• Intermittent behaviour: gears work sometimes, but not consistently
• Unusual resistance: selecting a gear requires more force than normal
• Noises when selecting gears: grinding or resistance when trying to engage
• Related drive issues: changes in pedal feel or hesitation when pulling away

These symptoms could be linked to gearbox problems, but they may also involve the clutch, transmission system or fluid levels. From a driver’s perspective, it’s difficult to pinpoint the exact cause without inspection.

Instead of guessing, it’s best to have it checked professionally. A nearby Bosch Car Service can assess why your car won’t go into gear, confirm whether the issue is gearbox-related and advise on the appropriate next step — from a simple adjustment to targeted gearbox repair if required.

Hearing new or unusual sounds while driving can be unsettling. Gearbox noise doesn’t always mean a serious fault, but it can be an early sign that something in the drivetrain isn’t working as smoothly as it should.

Drivers often notice:

• Whining or humming: especially at certain speeds or when accelerating
• Grinding sounds: during gear changes or when selecting a gear
• Clunking noises: when pulling away or changing load
• Noise that changes with gears: sounds appear only in specific gears or driving situations

These noises could be related to gearbox problems, but they can also come from low oil levels, wear in related components or other transmission issues. From the driver’s seat, it’s almost impossible to tell the exact cause.

Rather than ignoring the noise or guessing, it’s best to have it checked. A nearby Bosch Car Service can assess the source of the gearbox noise, determine whether it’s linked to the gearbox or another component, and advise on the right solution — from a simple service to targeted gearbox repair if needed.

If the engine revs increase but the car doesn’t pick up speed as expected, this could be a sign of gearbox slipping. It’s often subtle at first and may only appear under certain driving conditions.

You might notice things like:

• Delayed acceleration: the engine responds, but power isn’t transferred smoothly
• Inconsistent drive: the car feels hesitant or jerky when changing speed
• Slipping under load: problems become more noticeable when accelerating, going uphill or carrying passengers
• Gear changes feel unclear:the car doesn’t feel fully “engaged” in a gear
• Warning behaviour: performance varies between gears or driving situations

These signs can be linked to gearbox problems, but they don’t automatically mean the gearbox itself is damaged. Issues with fluid levels, wear in related components or the clutch can cause similar symptoms.

Because the cause isn’t always obvious, a professional check is the safest next step. A nearby Bosch Car Service can identify whether gearbox slipping is present, determine the underlying reason and advise whether a gearbox service or targeted gearbox repair is required.

Not every gearbox issue requires the same solution. Depending on the condition of the gearbox and how the car is used, different gearbox repair services may be suitable.

Gearbox repair

This focuses on fixing specific faults, such as leaks, worn components or minor internal damage. It’s often suitable when problems are detected early and the gearbox structure is still sound.

Gearbox reconditioning

Reconditioning involves removing the gearbox, stripping it down and refurbishing worn parts. A gearbox reconditioned service is typically chosen when wear is more advanced but a full replacement isn’t necessary.

Gearbox replacement

Replacement means fitting a new or reconditioned gearbox. This is usually required when damage is extensive, internal components are severely worn or repair is no longer reliable.

What influences which service is needed:

• Type and extent of damage: minor faults vs widespread internal wear
• Vehicle age and mileage: higher mileage can affect repair options
• Driving symptoms: noise, slipping or difficulty selecting gears
• Cost-effectiveness: repair vs long-term reliability
• Vehicle use: daily commuting, towing or heavy loads

Because every case is different, there’s no one-size-fits-all answer.

The best option is always an individual assessment. Experts at your local Bosch Car Service garage will inspect the gearbox, explain the available options and help you decide whether gearbox repair, gearbox reconditioning or gearbox replacement is the most suitable solution for your car.
