If your car makes loud noises when you put it into gear, it usually indicates a problem with the transmission, clutch, or driveline components. The noise could be grinding, clunking, or banging, and should be inspected immediately to avoid further damage or unsafe driving conditions.

What does it mean if there are loud noises when putting the car in gear?

Loud noises when shifting into gear suggest that something is worn, damaged, or misaligned in the drivetrain. It could be a clutch issue (for manual cars), torque converter fault (for automatics), or damage in the gearbox or driveshafts.

Common causes of loud noises when engaging gear

• Worn or damaged clutch components (manual cars)
• Low or contaminated transmission fluid
• Failing transmission gears or synchronisers
• Faulty torque converter (automatic cars)
• Damaged CV joints, driveshafts, or universal joints
• Loose or broken engine or transmission mounts

Why do you need to fix this problem quickly?

Ignoring loud noises when putting the car in gear can lead to complete clutch or transmission failure, leaving the vehicle undriveable. It may also cause further drivetrain damage and increase repair costs.

How do you know when to get it checked?

You should book an inspection if:

• You hear grinding, clunking, or banging when shifting into gear
• The car struggles to engage gears
• There are vibrations or jerks when shifting
• The clutch slips or doesn’t engage properly (manual)
• The transmission fluid appears burnt or low

What happens during an assessment?

A mechanic will:

1. Test drive the car to identify the type of noise
2. Check clutch operation (manual) or torque converter function (automatic)
3. Inspect transmission fluid condition and level
4. Examine mounts, driveshafts, and CV joints for wear
5. Diagnose whether the issue is within the gearbox or external components
6. Recommend repair or replacement of faulty parts

How much does it cost to fix?

Minor repairs like fluid changes or mount replacements may cost $200–$500. Clutch repairs typically range from $900–$1,800+, while major transmission repairs or replacements can cost $2,500–$5,000+.

Is it unsafe to drive with loud noises when engaging gear?

Yes. Loud drivetrain noises often signal major mechanical issues that could cause sudden failure, leaving you stranded or unable to control the vehicle safely. The car should be inspected immediately.
