M20 / M32 Manual Gearbox ProblemsM20 / M32 Manual Gearbox Repairs
The M20 and M32 Manual 6-speed gearboxes are extremely common failures and are fitted to a variety of vehicles including Vauxhalls, Alfa Romeo’s and Fiats. The most common problem is worn and noisy bearings which cause the gearbox to whine in certain gears. The noisy bearing may be more audible in some gears then others.

A noisy gearbox when treated quickly is not that bad a problem, we can generally re-bearing the box and have you back on the road in no time – but if you ignore a noisy bearing it can very quickly become a big problem.

Common M20 / M32 Manual Gearbox Faults

  • Gears Crunching
  • Stuck In Gear
  • Not Going Into Gear
  • Jumping Out of Gear
  • Noisy Gearbox (Whining / Grinding)
  • Gear Problems When Hot
  • Gear Problems When Cold

Although we’ve repaired hundreds of these gearboxes now, there’s many people that are not aware of Gearbox Repairs and will either pay out a lot for a brand new gearbox (which will come with a limited 12 months warranty) or pick up a cheap second-hand used gearbox (which will come with a limited 30-90 days warranty).
