Reconditioned Citroën C8 2.0 HDi Gearbox – Reference 20MB51

This reconditioned 6-speed manual gearbox is designed for the Citroën C8 fitted with the 2.0 HDi engine (1997 cm³), compatible with engine codes RHW (DW10ATED4), RHT (DW10ATED4) and RHK (DW10CTED4), under reference 20MB51. Choosing a reconditioned gearbox means restoring reliable performance without waiting for a new part to be manufactured, and at a more competitive price. Reconditioning involves a full strip-down, thorough cleaning and inspection of every component, followed by replacement of gears, synchros, bearings and seals as required by the wear found. The gearbox is then reassembled to manufacturer tolerances and bench-tested before dispatch, ensuring it meets original performance standards.

Signs That Your Gearbox Needs Replacing

On a C8 fitted with this 6-speed manual gearbox, several warning signs should prompt action before the problem gets worse:

  • stiff or grinding gear changes, particularly in 2nd and 3rd
  • a gear jumping out or refusing to engage fully
  • crunching or metallic noise in neutral
  • gear lever vibrating or jamming in position
  • oil leak from the gearbox casing
  • abnormal resistance or a stiff point when changing gear

Exchange Basis: Delivery Before Collection

This gearbox, reference 20MB51, is sold on an exchange basis, rebuilt to 0 km. The reconditioned unit is delivered first so that the garage is never left without a gearbox and the vehicle is not kept on the ramp any longer than necessary. The old gearbox, with its casing intact, is only collected after the reconditioned unit has been delivered and fitted to the C8. Return of the old unit is required, in accordance with our Terms and Conditions, and ensures the exchange is completed properly.

Compatibility

This gearbox, reference 20MB51, is compatible with Citroën C8 models fitted with the 2.0 HDi engine, carrying engine codes RHW (DW10ATED4), RHT (DW10ATED4) and RHK (DW10CTED4). We recommend checking the engine code on the vehicle's identification plate before ordering, to confirm exact compatibility with reference 20MB51.

Warranty and Payment

This reconditioned gearbox comes with a 24-month parts warranty, valid subject to fitting by a qualified professional. Payment can be spread over several instalments, in up to 10 instalments, subject to the options available at the time of ordering.

EDEN BOITES supports you from quote through to collection of the old unit.
