Gearbox Repair Kettering

Looking for Gearbox Repair Near Me? Automatic & Manual Specialists

Gearbox problems rarely fix themselves, and left unchecked they can turn a manageable repair into a full replacement. At Ronnie’s Garage, our gearbox repair service in Kettering covers both automatic and manual transmissions, from minor seal and linkage issues to full rebuilds, diagnosed properly before we recommend any work.

If you’ve noticed gearbox making noise, gearbox slipping, a car stuck in gear, or jerky changes on an automatic, it’s worth getting it looked at early — the difference between a repair and a full replacement often comes down to how quickly it’s caught.

Why Gearbox Repair Matters

Gearbox faults affect more than just how smoothly your car drives. Here’s why it’s worth sorting promptly:

Cost Control— Minor issues caught early are often a fraction of the cost of a full rebuild or replacement.
Reliability — A worn gearbox can fail unpredictably, potentially leaving you stranded or stuck in a single gear.
Safety— Difficulty selecting gears or unexpected slipping can affect your control of the vehicle, especially when overtaking or joining traffic.
Resale Value — Unresolved gearbox issues are a major red flag for buyers and can significantly affect your car's value.

At Ronnie’s Garage, we’ll always explain whether your gearbox needs a targeted repair, a rebuild, or a full replacement — and why — rather than defaulting to the most expensive option.

Your gearbox usually gives clear warning signs before it fails completely. Watch out for:

If you notice any of these, it’s worth booking a diagnostic check before the issue worsens.

FAQs About Gearbox Repair Kettering

Answers to common questions about our Gearbox Repair in Kettering.

How much does it cost to repair a gearbox?
The cost of gearbox repair depends on the type of gearbox, the nature and extent of the fault, your vehicle’s make and model, and whether repair or replacement parts are required. We’ll diagnose the issue and confirm the recommended work and cost before proceeding.
How do I know if my gearbox is failing?
Signs include grinding or crunching when changing gear (manual), jerky or delayed gear changes (automatic), difficulty selecting gears, unusual noises, or a gearbox warning light on the dashboard.

.
Is it cheaper to repair or replace a gearbox?
t depends on the extent of the damage. Minor internal wear is often cheaper to repair, while severe damage — such as a badly worn automatic gearbox or stripped gears — usually makes replacement the more reliable long-term option.



Can you drive with a faulty gearbox?
It depends on the fault — a manual gearbox with mild synchro wear may still be drivable short-term, but slipping, grinding, or a car stuck in gear should be checked promptly, as continuing to drive can cause further, more expensive damage.


What's the difference between repairing a manual and an automatic gearbox?
Manual gearbox repairs typically involve mechanical wear (synchros, bearings), while automatic gearboxes involve additional complexity from torque converters, hydraulics, and electronic control units, which is why automatic repairs tend to cost more.





Why is my automatic gearbox jerking when changing gear?
This is commonly caused by low or degraded transmission fluid, though it can also indicate a mechatronic or torque converter fault. A diagnostic check will identify the specific cause.


Does gearbox oil need to be changed regularly?
Yes — though intervals vary by manufacturer, gearbox oil degrades over time and can contribute to rough or delayed gear changes if left too long. A gearbox oil service typically costs £150–£350.



Should I replace the clutch when replacing a manual gearbox?
It's often recommended — since the gearbox has to be removed to access the clutch anyway, replacing a worn clutch at the same time avoids paying for the same labour twice in the near future.
