Car vibrations from engaging the reverse gear can be caused by several factors including worn engine and transmission mounts. Check out how to figure it out!

If you have been driving for some time, you might be familiar with this issue. Your car vibrates when you engage the reverse gear, making you wonder what the problem is. Obviously, there’s a problem somewhere. The question is: where is the problem from?

Car vibration can be caused by several factors. But given the context of the situation at hand, our experts at Naijauto have streamlined it to two factors in order to find a solution to the problem. These two factors include: engine mounts and worn transmission mounts.

1. Worn engine mounts & how to fix it

Steel and rubber are the components that make up the engine mounts. The major function of the steel is to ensure that the engine stays firmly on the car frame, so it doesn’t fall off. The rubber is saddled with the responsibility of absorbing the engine vibration and road shock whenever the car is put on. This ensures that the car driver attains some level of comfort while on the wheels without feeling the awkward engine vibration as the process of combustion is in motion.

The engine mounts perform this duty well only when they are in good condition. When they are worn out, they become incapacitated. This means that the engine will no longer be firm on the car frame. Its looseness makes the rubber part to be unable to absorb the engine’s vibrations.

Tracing worn engine mounts is difficult to some mechanics due to the technicalities involved. The vibrations might be caused by other factors they aren’t aware of. When it’s figured out that it’s caused by worn engine mounts, a replacement is needed immediately. Otherwise, you’ll continue to hear that disturbing sound when you turn on your car and when you leave it idle.

Do you hear a clicking sound? The motor mounts are either damaged or broken. Your mechanic has to properly inspect the condition to come up with the best way to fix it. He needs to check the rubber parts to see if they are unable to absorb the engine vibrations. Their contacts are similar to ligaments. When they are loose, vibration is inevitable.

Do you experience more vibration when you apply the first gear or try to reverse your car? During vibration, more pressure is exerted on the car, pushing it toward the point of vibration. Some car users revealed that they also experienced vibration in the driver’s seat. Have your expert mechanic replace the mounts.

2. Worn transmission mounts & how to fix it

Although the transmission mount is different from the engine mount, it performs a similar function. The major difference between both of them is that, while the engine mount holds the engine firmly to the car frame, the transmission mount holds the transmission box firmly to the car frame. They both function as a cushion, keeping vibration at bay.

Your driving comfort is jeopardized when your transmission mounts are in bad condition. This is because the mounts can no longer keep the gearbox in the position it’s meant to be. When the gearbox is shaky or loose, it makes indiscriminate contact with the engine parts, triggering vibrations that aren’t needed. It gets crazier when you engage the reverse gear because of the higher pressure inserted on the mounts.

Vibrations can also occur when the rubber parts of the transmission melt due to oil leakage from continuous friction in the gearbox. This is caused by the many activities going on in it. As time passes by, the rubber can also deteriorate as it has served its purpose.

How to fix worn transmission mounts

This is too complex for you to fix yourself. Go straight to a professional mechanic. When your mechanic is done with a proper visual inspection of the transmission mounts just as he did to the engine mounts, he’ll figure out which of them is causing the problem.
