Reconditioned BMW 5 Series 2.0d Gearbox – 6-Speed Manual – Ref. GS6-37DZ-THES

Reconditioned BMW 5 Series 2.0d Gearbox – Reference GS6-37DZ-THES

This reconditioned gearbox for the BMW 5 Series 2.0d, with an engine capacity of 1995 cm³, fits the engine variants identified by engine codes M47D20, N47D20A and B47D20, under reference GS6-37DZ-THES. This 6-speed manual gearbox is fully stripped, cleaned and inspected before reassembly: worn gears, synchros, bearings and seals are replaced as required, and the unit is then rebuilt to manufacturer tolerances and bench-tested before dispatch. This process ensures near-new performance, with smooth gear changes and reliable transmission from the moment the vehicle is back on the road.

Signs that your gearbox needs replacing

On a 5 Series fitted with this 6-speed manual gearbox, several warning signs point to advanced wear: stiff or grinding gear changes, crunching on downshifts, difficulty engaging third or fifth gear, noticeable judder during gear changes, vibrations felt through the gear lever or clutch, and sometimes a neutral that slips away when stationary. A dull noise in neutral, increased resistance when selecting reverse, or an oil leak from the casing can also indicate internal failure. These symptoms are generally caused by worn synchros or internal bearings and justify replacement of the GS6-37DZ-THES gearbox.

Exchange basis: immediate delivery, return of the old unit deferred

This gearbox is sold on an exchange basis: the reconditioned unit is dispatched to your garage first, without waiting for the old gearbox to be returned. The original casing or block, kept intact, is only collected after the reconditioned gearbox has been delivered and fitted, so the vehicle is never left off the road. This arrangement allows your garage to carry on working without waiting for the old unit to be returned. Return of the old unit is nonetheless required, in accordance with our Terms and Conditions.
