Mercedes-Benz Gearbox Replacement Repair Cost

A reconditioned (remanufactured) gearbox typically costs £300–£1,200 for the unit, plus £400–£800 labour. A new OEM gearbox can cost £1,000–£3,000+ for the part alone. The total bill depends heavily on vehicle make and model — specialist and performance cars sit at the top end.

Worn synchromesh rings or bearings can often be rebuilt at lower cost than full replacement. However, if the gearbox casing is cracked, multiple internal components have failed, or a repair estimate exceeds 70% of the replacement cost, a reconditioned unit usually offers better value and reliability.

Common signs include difficulty engaging gears, a grinding or crunching sensation when changing gear, the gearbox jumping out of gear unexpectedly, whining or humming at certain speeds, and a burning smell from the gearbox area. Catching these early can mean the difference between a repair and a full replacement.
