A gearbox that slips, shudders or refuses to change gear needs looking at early. We diagnose the fault, explain whether servicing or repair is the answer and agree the estimate before we start.
An automatic gearbox does a lot of quiet work, using fluid pressure, clutches, sensors and a control unit to pick the right gear for you. When it goes wrong the first signs are often small: a slight delay when you select drive, a flare of revs between gears, or a harsh bump on a pull-away.
MTS Garage Services, an independent family-run garage in Hayes, handles automatic gearbox repairs and Automatic Transmission Servicing Hayes drivers can book directly. We also see cars from Southall, Uxbridge and Hounslow, and we always start with a proper diagnosis rather than assuming the box is finished.
Pay attention if the car hesitates before engaging drive or reverse, if the revs rise without the car pulling forward, or if changes feel rough or late. A whining or humming noise, a burning smell, fluid on the driveway or a gearbox warning light are also reasons to stop putting it off. Some cars drop into a limited mode that holds one gear to protect the box, which can feel like the car has lost power. That is a message, not a cure. Driving on usually adds wear, so book it in as soon as you can and tell us exactly what the car does.
Many automatic faults are not the gearbox itself. Low or degraded fluid, a faulty speed sensor, a failing solenoid, a wiring problem or a software fault can all mimic a worn transmission. We check the fluid level and condition, read fault codes from the transmission control unit, look at live data and test the connected components. Only when that points to internal wear do we discuss bigger work. You will hear the findings in plain language, along with what we recommend and the options open to you, before any repair is agreed.
Automatic transmission servicing is often the sensible first step towards a calmer box, but only when the fault is caused by tired fluid or a clogged filter. Servicing typically involves:
If the diagnosis shows internal damage, there are usually choices: repairing the fault, fitting a reconditioned unit or replacing the gearbox. Which is sensible depends on the car, the fault and what you want from it, and we will talk it through honestly without pushing you toward the largest job. The estimate depends on the make, the type of automatic and what we find. We do not give rebuild times up front, because they depend on the unit and parts.

“Always my go to, reliable, friendly”
“Great garage, really helped me with my car. Got a clutch done and they picked it up for me as I didn't have a way to get it to them. really nice people to deal with. Thank you”
“These guys are brilliant. Super-friendly, super-knowledgable and first class service.”
Many do, even though some makers describe the fluid as lifetime fill. Fluid breaks down with heat and use. Check your handbook and tell us the make, model and mileage, and we will advise whether a service makes sense for your car.
No. Low fluid, a failed sensor or a faulty solenoid can cause slipping and are far smaller jobs than internal repair. That is why we test before recommending anything. Ignoring it for long can turn a small fault into a larger one.
Avoid long journeys where you can. The car may be in a protective mode, and continued driving can add damage. If it is behaving oddly or smells of burning, stop safely and call us for advice.
We handle a range of transmissions and have a separate page for DSG gearbox repairs. Give us the make, model and year when you get in touch and we will tell you what we can do.
