The Alfa Romeo 6 speed gearbox can suffer from differential (diff) failure which often punches a hole in the gearbox through to the clutch. On some occasions the clutch fails and punches part of the clutch through the gearbox casing into the differential causing the gearbox to fail.

Many people chose to fit a Q2 differential which will prevent the failure

Here the original differential along with a Q2 limited slip differential is pictured

Q2 fitted to a car in situ £600

Q2 fitted to a supplied gearbox £450

Full gearbox rebuild and Q2 after diff failure £1000
(exchange or supplied gearbox)

Many customers have their local garage remove their gearbox and we organise a courier to collect the gearbox and bring it to us where we rebuild it, fit the Q2 and courier it back to the garage. We can organise this from most countries.

*It is the responsibility of the garage or person fitting the gear box to ensure that the oil is added as the gear box will be shipped dry.

To remove the gearbox from the car, rebuild the gearbox fitting a Q2 differential and refitting £1,300, it is often a good idea to replace the clutch if this work is being carried out (this excludes the Alfa Romeo 166)

With our rebuilt gearboxes we offer a 12,000 mile or 12 month warranty, which ever comes first. Here are the terms of our warranty:

Oil levels must be checked regularly as oil starvation will void the warranty. After 500 miles, the oil must be checked.
