Alfa Romeo Gearbox & Engine Repair Specialists in London

Why is my Alfa Romeo juddering or shuddering when pulling away?

This is the most common complaint we hear from TCT-equipped Alfa Romeos. The Giulietta, Giulia, Mito and Stelvio are the models we see most often. The judder happens because the dual-clutch pack and mechatronic unit wear over time, and smooth pull-away goes with it. It is most noticeable in slow-moving traffic, on hills or when reversing. Some owners put up with it for months assuming it is normal. It is not. Left long enough, worn clutch packs cause further internal damage to the mechatronic unit. A TCT diagnostic will confirm the fault within an hour.

We rebuild and recondition TCT units in London. Most jobs are completed in one to two days*.

What does the TCT warning light mean on an Alfa Romeo?

A gearbox warning light on an Alfa Romeo typically indicates the mechatronic unit, clutch pack or a transmission sensor has detected a fault. The most common causes are mechatronic unit failure, low hydraulic pressure, a worn position sensor, or a clutch pack that has gone beyond its wear limit. In some cases the car will refuse to select gears and go into a safe or limp mode. Do not ignore a gearbox warning light. The TCT system relies on hydraulic pressure and electronics, and running it with a fault will accelerate mechatronic and clutch wear.

We have the specialist software to read Alfa Romeo gearbox fault codes and the parts to fix TCT units properly. A diagnostic starts from £30.

How much does an Alfa Romeo gearbox repair cost in London?

It depends on the gearbox type and the fault. A TCT mechatronic overhaul and a Q4 automatic torque converter replacement are very different jobs in terms of parts and labour. Our prices are up to 60% less than an Alfa Romeo main dealer for the same quality of work using approved parts. We quote a fixed price before we start. There are no hidden charges and the £30 diagnostic fee comes off your repair bill if you go ahead.

Can I drive my Alfa Romeo with a gearbox fault?

Some faults allow short journeys but most get worse quickly under load. If your Alfa Romeo has a gearbox warning light, is slipping out of gear on the motorway, is refusing to select drive or reverse, or is making grinding or clunking noises, you should not drive it further than necessary. Continuing to drive with an active gearbox fault almost always turns a repairable problem into a full rebuild or replacement. We offer vehicle recovery across London if your car cannot be driven to us.

Is it worth repairing an Alfa Romeo gearbox or should I replace it?

Repair or reconditioning is almost always cheaper than replacement. A full gearbox replacement is expensive regardless of who does it. The majority of Alfa Romeo gearbox faults are repairable. TCT mechatronic failure, clutch pack wear and fluid leaks can all be fixed without replacing the whole unit. We diagnose first, quote second, and only start work when you approve it. We will only recommend a full replacement if the unit is beyond economic repair. You will not be sold unnecessary work.

Will repairing my Alfa Romeo gearbox affect my manufacturer's warranty?

No. Under Block Exemption legislation you have the legal right to use any qualified independent specialist without voiding your Alfa Romeo manufacturer's warranty. The only conditions are that approved parts are used and the technicians are qualified. We meet both requirements on every job. This applies whether your car is still under the original warranty or an extended warranty. You do not have to go to an Alfa Romeo main dealer to keep your warranty intact, and you will almost certainly pay significantly less with us.

What are the most common Alfa Romeo TCT gearbox problems?

The TCT dual-clutch unit fitted across the Alfa Romeo range has a few well-documented fault patterns. Mechatronic unit failure is the most common and is responsible for most warning lights and gear selection problems. Clutch pack wear causes the characteristic shudder on pull-away. Solenoid faults lead to jerky or delayed shifts. Oil contamination from a failed seal can damage multiple components at once. On Q4 automatic models, torque converter wear is a primary cause of harsh shifting and shudder. Early diagnosis on all of these prevents much more expensive consequential damage.
