Reconditioned Toyota Proace 1.6 D-4D Gearbox – 5-Speed Manual – Ref. SU001A3122

Reconditioned Gearbox SU001A3122 – Toyota Proace 1.6 D-4D

The reconditioned SU001A3122 gearbox fits the Toyota Proace 1.6 D-4D, a diesel van with a 1560 cm³ engine whose 5-speed manual transmission takes a heavy beating day in, day out. This SU001A3122 reference is in high demand for this model, as wear to the synchromesh rings and internal bearings inevitably makes itself known over the kilometres. Reconditioning involves a full strip-down of the gearbox, thorough cleaning and inspection of every component, followed by replacement of all internal wear parts: gears, synchros, bearings and seals. The unit is then reassembled to manufacturer tolerances and bench-tested before dispatch, ensuring performance that matches the original specification.

Signs That Your Manual Gearbox Needs Replacing

Several symptoms point to a failing SU001A3122 gearbox: stiff or imprecise gear changes, crunching or grinding when changing down, clutch judder, gears jumping out whilst driving, or difficulty finding neutral. On a Proace used for deliveries or in heavy-duty service, these signs often appear sooner due to the loads carried and the repeated demands placed on the transmission.

Exchange Basis: Immediate Delivery, Return Later

This gearbox is sold on an exchange basis, rebuilt to 0 km: the reconditioned unit is delivered straight away, without waiting for the old gearbox to be removed first. Your old gearbox, with its casing intact, is only collected after the SU001A3122 has been delivered and fitted, so the vehicle is never off the road any longer than necessary. Return of the old unit is nonetheless required, in accordance with our Terms and Conditions.

Warranty and Payment

The SU001A3122 gearbox comes with a 24-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over several instalments, in up to 10 instalments, to help manage your budget.
