Reconditioned Citroën Jumper 2.2 HDi Gearbox

4 engine codes for two distinct gearboxes on the Jumper 2.2 HDi

On the Citroën Jumper 2.2 HDi produced from 2006 to 2021, the transmission is exclusively manual — no automated manual, no dual-clutch. Yet this apparently uniform mechanical setup actually covers two families of manual gearboxes, 5-speed and 6-speed, which are not interchangeable depending on the engine code stamped on the block.

4HV, 4HU, 4HG, 4HH: the engine code determines the gearbox

The four engine codes listed — 4HV, 4HU, 4HG and 4HH — correspond to different power outputs and emissions standards within the same 2.2 block. Each variant is paired with a specific gearbox: some take the 5-speed, others the 6-speed. Mixing them up on a commercial vehicle used under load means fitting a mechanically incompatible part. Before placing any order, the engine code — not just the engine capacity — is the critical reference.

Known weaknesses of the 2.2 HDi in commercial use

Under repeated load and intensive use, the gearboxes fitted to the Jumper 2.2 HDi suffer accelerated synchromesh wear, particularly on the lower gears engaged during unladen manoeuvring or climbing hills under load. Difficult gear changes in 2nd and 3rd, accompanied by noise on the clutch, are generally a sign of advanced deterioration before any outright failure. EDEN BOITES stocks gearboxes covering the full 2006–2021 period for this application, with specific references for each engine code.
