Gears Slipping When Accelerating Inspection

What Does It Mean By Gears Slipping?

Slipping gears can occur in a manual or an automatic vehicle and means your vehicles won’t change gears smoothly.

It struggles to engage into gear, resulting in a delay before it engages.

On some vehicles a warning light may illuminate on your dash, alerting you to a problem.

Other signs your transmission is slipping can be grinding noises, a burning smell, engine revving higher, or your vehicle may pop in/out of gear,
or even into the wrong gear, without warning.

If your vehicle experiences any of these symptoms, your transmission should be inspected as soon as possible.

It’s also a good idea to have a look on the ground, where the vehicle is usually parked, to see if the vehicle has been leaking transmission fluid.

A slipping gears inspection can cost approximately $40 to $150, depending on the time taken to identify the problem.

A technician will look over the vehicle, suggest repairs and supply a quote for the repair.

How Do Gears Work?

There are many variants when it comes to transmissions.

In the old days it was just manual or automatic, but with new technology comes diversity and now cars may have CVT, DCT, Automated-Manual, Direct Shift or Tiptronic Transmissions.

A manual transmission comes with a gear selector and a clutch.

The clutch engages and disengages the drive shaft and is manually operated by the driver.

The gears need to be manually changed in conjunction with disengaging and engaging the clutch.

Automatic transmissions connect to the engine via a bellhousing which contains a torque converter.

The torque converter is used instead of a clutch.

The driver can manually assist in gear changes, if desired, or leave it up the converter to do the job.

No matter what type of transmission you have, they all use multiple gear ratios that work in accompaniment with the engine’s speed and torque, keeping it within the desired powerband, to move the wheels.

As you can imagine, with so many moving parts, there is a lot of heat and friction, which is why your transmission uses a specific lubricant to
ensure the gears move freely and avoid overheating.

Transmission fluid needs to be replaced at specific service intervals to maintain optimal performance of the transmission.

Common Reasons Gears Slip When Accelerating

  • Low transmission fluid level 
  • Burnt transmission fluid 
  • Transmission leak
  • Worn synchronisers
  • Contaminated fluid
  • Worn out clutch
  • Towing excessive weight 
  • Transmission dying, lifespan reached

How Is A Gear Slipping Inspection Performed?

The technician will ask what symptoms you have been experiencing and take the vehicle for a test drive to see if they can replicate and identify the issue of concern.

The technician will check the transmission fluid, looking at the levels, colour and quality of the fluid and also look under the vehicle to see if there are any obvious transmission leaks. 

A computer may be linked up to your car to check for any transmission error codes. 

The technician will then give you their diagnosis and estimated cost to repair. 

How Important Is The Gear Slipping Inspection?

If you're wondering if you should drive while your gears are slipping, the answer is no. 

It is unsafe to continue driving with this condition and the chances are high that your vehicle could unexpectedly jump into our out of gear, putting you in a precarious situation. 

Imagine pulling out to overtake someone and you try to accelerate but nothing happens. 

That's not a desirable situation to be in.
