Mobile Automatic Gearbox Servicing - Renfrewshire

Automatic gearboxes need servicing just as much as the engine does, even though it’s easy to overlook. Motorway Assist carries out automatic gearbox servicing at your home or workplace across Renfrewshire, helping to keep gear changes smooth and avoid costly transmission problems further down the line.

Signs your automatic gearbox needs servicing

• Gear changes that feel delayed, jerky or hesitant.
• A burning smell, which can indicate old or degraded transmission fluid.
• Slipping between gears or revs rising without matching acceleration.
• Warning lights related to the transmission system.
• No record of the gearbox oil having been changed within manufacturer intervals.

What’s involved in a gearbox service

We drain and replace the transmission fluid and filter where applicable, using the correct specification fluid for your vehicle, since automatic gearboxes are far more sensitive to the wrong fluid type than most drivers realise. We’ll also check for any fault codes stored in the transmission control unit using our diagnostic equipment, which can catch developing issues before they turn into a major repair.

Why servicing intervals matter

Manufacturers often describe automatic transmission fluid as lifetime fill, but in practice most gearboxes benefit from a fluid change at set intervals, particularly on cars used for stop-start driving or towing. Skipping this can shorten the life of the gearbox considerably, and a replacement transmission is a significantly bigger expense than routine servicing.

Get in touch to find out when your automatic gearbox is due a service, and we’ll come to you to carry it out.

The cost of skipping a gearbox service

Automatic gearboxes are considerably more expensive to repair or replace than to maintain, and by the time slipping or hesitant gear changes become noticeable, wear may already be underway. Regular fluid changes at the right interval help the gearbox run smoothly for longer and reduce strain on its internal components, which is a far cheaper habit than waiting for a fault to develop.

Why the right fluid matters

Automatic transmission fluid isn’t a one size fits all product. Different gearboxes are designed around specific fluid types, and using the wrong one can affect shift quality or, in some cases, cause damage over time. We always use the correct specification for your vehicle, rather than a generic fluid that happens to fit the same fill point.
