Why Does Your Car Clunk When Shifting Into Drive Or Reverse?

Sometimes, you find that your car experiences a clunk when shifting into drive or reverse, and you do not know why?

Although there are numerous causes for this condition, it would be preferable if you could eliminate the noise as quickly as possible.

The following information in this post will give you the most critical elements to consider and how to cope with them. So, stay tuned and keep reading!

Why Does Your Car Clunk When Shifting Into Drive Or Reverse?

The clunking noise when shifting from reverse to drive can come from the brake issues, the transmission fluid being too low or too old, or sensors miscorrecting information about your speed or displacement during transmission.

Internal components malfunctioning and damaged or loose transmission/engine assembly also generate noises in your vehicle.

Transmission Fluid Is Too Low Or Too Old

Automatic transmission fluid is needed to provide enough lubrication to allow for efficient gear shifting.

Appropriate lubrication and cooling get problematic whenever the trans fluid levels are too low or too old. Such poor fluid can also trigger humming noise when accelerating.

To prevent clunk noise when shifting from park to reverse, you should examine the liquid level and its color to see if this is the issue.

The proper fluid must be clean and reddish-pink. Whether it is turbid, black, or brown, it has been tainted, old, or burnt.

Sensors During Transmission Are Incorrectly Adjusting Your Displacement Or Speed Information

This problem is something you should look into when you reverse into drive and it makes a clunking sound. Computer sensors now monitor many automotive transmissions.

Clunking noise in transmission is typically created by sensors transmitting inaccurate movement or motion information, resulting in issues owing to improper tuning.

Problems With Internal Components That Cause The Vehicle To Shift Too Forcefully Or Incorrectly

Spring, bearings, and gears are among the compounds contained inside your gearbox.

In each of the following particular sequences, the transmission operates smoothly, and issues with one of them might generate a clunk sound when shifting gears.

Once you are experiencing this situation with your car a couple times, disassemble the transmission to diagnose the damage effectively.

Damaged Or Loose Transmission Or Motor Assembly Causing The Transmission To Move

If your transmission bracket or engine mount is loose or cracked, you may notice a humming sound when you reverse or drive due to rack movement.

In this case, you should have the mechanics check whether this is the issue. They will examine the components beneath your vehicle to come up with the right solution.

It is also conceivable that the clunking sound when shifting from park to reverse, which you believe emanates from your transmission, is caused by faulty joint couplings.

What Are Tips To Deal With Clunking Noise When Shifting From Park To Drive?

Tips To Deal With Clunking Noise When Shifting

Now that you have clarified where the loud clunk comes from when you shift from park to drive, we have some tips for getting rid of them.

Search For The Reasons Why That Noise Happened

The first step is to spot any unusual loud clunk sounds coming from your vehicle. Accepting that your car has an issue that should be corrected as quickly as feasible will be helpful.

While driving, shut off your radios, video clips, conditioning systems, or any other sources of sound, including any small talk in your car, and listen closely to determine what is creating the sound and what needs to be changed.

After determining the noise source, look for any missing bushings, components, or gaskets that may need to be replaced or tightened.

If unsure about your ability to repair the issue, you should take your vehicle to an automotive mechanic. They will investigate the cause of the clunk when shifting into drive and resolve the issue for you.

To minimize accidents related to missing particular parts, you should have your vehicle fixed as soon as feasible.

Be Sure Of The Pre-Installed Components That Dampen The Sound

Another suggestion for reducing clunking noise when putting car in reverse is to inspect the sound-absorbing system.

Sound target reduction elements are pre-set to keep your brake quiet and your ride quality silent and smooth.

However, if these components are out of order or are accidentally dropped, your vehicle could become raucous.

As a result, you must ensure that all sound reduction features are in place. Check the section below where the flame retardant gasket functions as a substance to block off heat and sound from the engines.

The patches can become broken over time, rendering them to become loose when dangling or out of order.

Also, the clunk from park or the clunk in reverse can be produced by misplacing the rubber gaskets on your doors and windows.

It would be best if you also inspected these pieces to see whether they need to be replaced or have been misplaced.

Choose The Right And Narrow Tire For Your Car

Besides correct fluid, appropriate narrow tires will lessen the noise from your vehicle. Indeed, studies have shown that 18-inch tires produce more sound than 16-inch tires.

Additional Soundproofing System

Clunking when shifting into reverse can cause fatigue and stress while driving. It significantly explains why you feel exhausted after a long road trip.

If you want the car to run more quietly, you can install special soundproofing materials.

Frequently Asked Questions

What Does A Clunk When Shifting Into Reverse Mean?

The clunk noise when shifting gears means that if your car rattles when you press the auto-parking brake, the brake rotor, calipers, or bad brake pads are severely worn or broken.

If the crash happens while you drive over a bump, there could be an issue with the foundation, or a piece of the exhaust could fall loose.

When your automobile rattles when driving, the issue could stem from the wheel, wheels, and tires or old wheel bearings.

How Does A Knock Transmit Sound?

What you’re truly hearing if your engine is knocking is a fuel burning irregularly in the vehicle’s cylinders.

The little fuel canisters will ignite piece by piece, evenly spaced, with a balanced combination of air and fuel.

When that mix is broken, the shock of those bad gasoline bags being consumed at the incorrect moment creates knocks and shudders, which can endanger the drive gear’s cylinders.

Can Low Transmission Fluid Cause Knocking?

You should be concerned if you start to hear these sounds when changing gear.

Low transmission fluid and worn gears can produce creaks, and computer and solenoid detectors can produce squeaks if they give incorrect data to your vehicle’s gearbox.


That’s all there is to understand about the clunk when shifting into drive or reverse. Now, you should have a method to maintain your drive gear efficiently on any route.

We wish you a wonderful driving experience. See you next time!
