Reconditioned Citroën Gearbox

18 Citroën models, three families of automated manual gearbox: where the faults are concentrated

On Citroën vehicles, gearbox failures don't all stem from the same cause. The automated manual gearboxes —SensoDrive and BMP6— found on the C2, C3 and certain versions of the C4 — are the most frequently reported: their electro-hydraulic actuator wears out under repetitive urban driving, resulting in jerky gear changes and, eventually, an inability to select certain gears. The ETG6, fitted to the C3 and C4 Cactus, displays similar behaviour. On the HDi manuals — 1.6, 2.0, 2.2 and 2.8 — the problem is different: it is the 2nd- or 3rd-gear synchromesh that wears prematurely, with difficult cold engagement as a classic early warning sign. A full replacement with a reconditioned gearbox often becomes the most reliable solution once these thresholds are reached.

Identifying the right part: the pitfalls specific to the Citroën range

The sheer variety of engine codes makes identification tricky. On the1.6 HDialone, codes range from 9HF to 9HZ, BHY, DV6FC and DV6FDU — each potentially corresponding to a different gearbox depending on the power output and generation of the vehicle. The same logic applies to the2.0 HDiwith codes RHH, RHK, RHR, RHT, RHV, RHW, RHY and RHZ: confusing two similar codes can lead to ordering an incompatible gearbox. On the1.2 PureTech(codes EB2DT, EB2DTS, EB2ADTS, HNZ…), the ETG6 automated manual gearbox sits alongside conventional manuals depending on the variant: the transmission type must therefore be confirmed before placing any order.

Light commercials — Jumper, Jumpy, Berlingo: gearboxes in a class of their own

TheJumper— with its 3.0 HDi codes F1CE0481D and F1CE3481E, or the 2.8 HDi 8140.43S — takes gearboxes of a fundamentally different design from passenger-car units: heavier-duty and dimensioned for high payloads. The Jumpy and Berlingo share part of their platform with the Peugeot Expert and Partner, which multiplies the possible cross-references: only the engine code stamped on the block, combined with the year and variant, makes it possible to pinpoint the correct reference. EDEN BOITES covers this entire range, from the Saxo and Xsara through to the Spacetourer, across model years from 1987 to 2026.
