What causes broken reverse gear teeth?

Damaged reverse gear teeth are usually caused by drivers who are either newbies or by someone who is careless when they are driving a manual transmission car. Other causes of reverse gear teeth breakage may also be linked to excessive wear and tear.

Therefore, if you want to avoid issues that deal with broken reverse gear teeth, you need to understand the cause, how to identify the symptoms, the types of repairs that need to be performed, and the associated cost involved.

With that said, let’s discuss this topic in a little more detail.

Causes of Broken Reverse Gear Teeth

Damage caused by inexperienced and careless drivers

Even though broken reverse gear teeth can affect the drivability of automatic transmission cars, one of the primary causes of broken reverse gear teeth is normally inexperienced or careless manual transmission drivers.

For instance, whenever a new driver does not shift gears in a manual transmission properly (i.e. struggles or forces gear changes), it is relatively easy to break critical components in the manual transmission including the reverse gear teeth.

Damaged Caused by Wear and Tear

Just like any other moving part in a vehicle, the reverse gear teeth in a manual transmission car are often subject to wear and tear over time.

In these situations, the wear and tear may also lead to broken reverse gear teeth and it will need to be repaired. For instance, after many years of constant use, the points on the gears begin to wear down.

As a result, the clutch will be out of proper adjustment, and this usually results in the 2 transmission shafts not stopping completely.

What are the symptoms of reverse broken gears teeth?

How do you know when your reverse gear teeth are broken? The signs and symptoms of broken reverse gear teeth may not be too difficult to spot when they arise. Yet, you need to become familiar with what they are before you are sitting on the side of the road.

Clicking Sounds

Typically, if you start to hear clicking noises when you are shifting gears, you may know that you have a problem with your reverse gear teeth.

For instance, if you are shifting from “P” Park to “R” Reverse, these sounds may appear to come from your CV joint or the motor mount. However, the problem usually leads to issues with broken reverse gear teeth.

Loud Clunking Sounds

Another symptom of this type of problem is the sound of loud clunking. Normally, these sounds may begin to grow louder whenever the driver shifts from park or other gears into reverse.

Also, if you are hearing these loud sounds as you are switching gears, you need to stop and seek help from a professional mechanic as soon as possible. If you do not, you will eventually lose your ability to shift into reverse.

The Car Will Not Move into Reverse

The most severe and critical stage in dealing with broken reverse gear teeth is not being able to shift into reverse. Simply put, anyone who has this type of car problem will not be able to back up until the issues have been identified and repaired.

How to fix broken teeth in gear?

If you have broken reverse gear teeth, you will not be able to drive your vehicle until it has been repaired. Since your car will only give you the capability to drive forward, it will not be safe to drive on the city streets or the highways.

For that reason, you will need to contact a professional mechanic to review and identify the problem so that it can be fixed properly.

Once the mechanic has inspected the vehicle to see what needs to be done, they will also have a chance to provide the most practical solution to resolve these issues.

First off, it is important to note that broken or damaged reverse gear teeth cannot be repaired. Instead, this type of component has to be replaced with new parts.

Additionally, the process of replacing broken reverse gear teeth is considered to be quite tedious and time-consuming. This is primarily because the entire transmission will need to be disassembled and then assembled again.

This is a process that should only be done by professional mechanics that possess the knowledge, skills, and experience to complete it accurately.

How much does it cost to fix the reverse gear teeth?

The average cost of repairing broken reverse gear teeth usually varies based on different factors. It is one of the most expensive jobs that can be done by a mechanic.

For instance, one of the biggest cost factors is the labor involved in removing the transmission to replace the reverse gear teeth that have been broken.

Also, because these types of repairs should be done by a professionally qualified mechanic, the price tag can be quite hefty. So, here are a few things that you should expect.

Prices normally vary based on the type of transmission in the vehicle. For instance, you may pay more for foreign versus domestic transmission jobs, since they can range in price from about $1200 – $1500 to $4600 – $5000.

The variances in price are usually related to the number of hours for the labor and the cost of the parts.


There are at least 2 common causes of broken reverse gear teeth that you need to be aware of, excessive wear and tear, and operating manual transmission cars improperly.

Whatever the circumstances, the driver will lose their capability to drive in reverse.

These repairs will often require the services of a qualified professional mechanic to replace and repair the vehicle’s transmission. And though the cost can vary, these repairs are relatively expensive to perform correctly.
