Reconditioned Renault Trafic 2.5 dCi Gearbox

5-speed manual, 6-speed manual or Quickshift: which gearbox does your Trafic 2.5 dCi actually have?

The 2.5 dCi in the Trafic covers two distinct engine codes — G9U 630 and G9U 730 — produced from 2003 to 2014, and these two units do not necessarily share the same gearbox. The configuration varies depending on the engine code, the power output (115 or 146 hp depending on the variant) and the body style (panel van, combi, chassis cab), which explains why three types of gearbox coexist across this range.

G9U 630 or G9U 730: an identification detail that changes everything

The G9U 630 corresponds to the early 2.5 dCi versions producing 115 hp; the G9U 730 is associated with the 146 hp variants that followed. This code, stamped on the block, is the only reliable reference for determining which gearbox reference matches your vehicle. The 6-speed manual (type PK6) is the most common on the 146 hp versions, whilst the 5-speed manual (type PF6 or NE3) is more frequently found on the earlier generations or certain lower-powered variants. The Quickshift (6-speed automated manual gearbox) is also available on this engine; this gearbox is supplied without its actuator.

Key points to watch on the 2.5 dCi in heavy commercial use

The Trafic 2.5 dCi is frequently used at maximum load or for towing, which places greater strain on the synchromesh rings and selector mechanism — particularly on 5th and 6th gear in 6-speed gearboxes. Difficulty selecting these gears when hot is a well-known symptom on high-mileage PK6 units. On 5-speed units, it is the differential and the reverse gear pinions that account for the majority of recorded wear. EDEN BOITES offers two purchasing options on this range: a reconditioned unit available for immediate dispatch, or a rebuild of your own gearbox with the same unit returned to you.
