Gear Box Mounting Replacement
Gear Box Mounting Replacement in Ajman — Marwat Garage Ajman
A thud when you shift into gear. A vibration through the floor that was not there before. A clunking sound when you accelerate or decelerate sharply.
These are not random noises. They are the symptoms of a failing gear box mounting — and ignoring them leads to damage that goes well beyond the mounting itself.
At Marwat Garage Ajman, gear box mounting replacement is a service we diagnose and carry out regularly. Here is what you need to know.
What a Gear Box Mounting Does
The gearbox — whether manual or automatic — is a heavy, constantly vibrating component. It cannot be bolted directly to the vehicle chassis without some form of isolation, or the vibration would transfer straight into the cabin and the driveline.
The gear box mounting — also called a transmission mount or gearbox support — is a rubber-and-metal bracket that holds the gearbox in place while absorbing vibration and preventing excessive movement.
It does two jobs simultaneously: support the weight of the gearbox, and isolate the rest of the vehicle from the forces the gearbox generates during operation.
When the rubber element of the mounting deteriorates, it can no longer do either job properly.
How Gear Box Mountings Fail
- Rubber deterioration is the primary cause. The mounting’s rubber core hardens, cracks, and eventually collapses under the weight and stress it carries. In Ajman’s heat, this process happens faster than in cooler climates — rubber components exposed to extreme temperatures age significantly quicker.
- Oil contamination accelerates failure dramatically. If an engine oil or gearbox fluid leak allows oil to contact the mounting rubber, the rubber swells, softens, and loses its structural properties rapidly. The mounting may look intact from the outside but have no effective damping left inside.
- Age and mileage eventually wear any mounting down. High-mileage vehicles — particularly those that have not had the mounting inspected during regular servicing — commonly present with collapsed or cracked mountings.

Symptoms That Point to a Failing Gear Box Mounting
- Clunking on gear changes A noticeable thud or clunk when shifting — especially engaging Drive or Reverse from Park on automatics, or shifting between gears on manuals — is one of the clearest signs. The gearbox is moving more than it should when torque is applied.
- Vibration through the floor or gear lever Excessive vibration felt through the cabin floor, the seat, or the gear lever at idle or under load suggests the mounting is no longer isolating the gearbox effectively.
- Knocking sound under acceleration or deceleration When you accelerate hard or lift off the throttle suddenly, the drivetrain torque reversal causes the gearbox to move. A worn mounting allows this movement to become a knock or bang transmitted into the cabin.
- Visible movement of the gearbox With the vehicle on a lift, a technician can check for excessive gearbox movement by applying load with the engine running. Movement beyond the normal tolerance is a definitive sign.
- Driveshaft or CV joint wear A gearbox that is sitting out of its correct position — due to a collapsed mounting — puts incorrect angles on the driveshafts and CV joints, accelerating their wear. If driveshaft problems keep returning after replacement, check the gearbox mounting.
Replacement Process at Marwat Garage Ajman
The vehicle is lifted and the underside inspected. We check the gearbox mounting alongside the engine mounts — these components work together, and a failed gearbox mounting often means the engine mounts are under additional stress and may need attention at the same time.
The gearbox is supported safely before the old mounting is unbolted. Removing support from the gearbox without proper equipment risks damage to surrounding components. The old mounting is removed, inspected, and the mounting points cleaned of rust and debris.
A quality replacement mounting is fitted and torqued to manufacturer specification. The gearbox support is removed and the drivetrain checked for correct alignment.
The vehicle is test driven to confirm the symptoms have resolved before handover.
The service takes approximately six hours. A one-month warranty is provided on the replacement.
Frequently Asked Questions
We now have an FAQ list that we hope will help you answer
some of the more common ones.
The cost varies depending on your car’s make, model, and the type of key system it uses. Basic remote key fob programming is affordable, while smart key and proximity key programming for newer vehicles may cost more due to the advanced software required. Call us on +971-564761112 for a specific quote for your car.
In most cases, yes — but it depends on the make and model. Some vehicles require at least one working key to programme a new remote, while others allow a complete key replacement via OBD2 access. Our technicians will advise you after a quick diagnostic check.
If a fresh battery has not solved the problem, your key fob may have lost its synchronisation with the car’s ECU — this is a common issue after a battery change or flat car battery. The fix is a simple reprogramming, which we can do while you wait at our garage in Ajman.
Most key fob programming jobs take between 30 minutes and one hour. Smart key programming for newer models may take slightly longer if it requires extended ECU communication. We will give you an accurate time estimate when you bring in your vehicle.
We can source compatible replacement key fob shells and remotes for most popular vehicle makers sold in the UAE. If you already have a new fob, we can programme it for you. Call ahead to confirm availability for your specific model.
