Reconditioned Fiat Ducato 2.5 TD Gearbox

Which manual gearbox fits the Ducato 2.5 TD, depending on the year and engine code?

The Ducato 2.5 TD is fitted exclusively with a 5-speed manual, without exception throughout the entire 1990–2002 period. The difficulty lies not in the type of transmission but in identifying the correct reference precisely, as two engine codes exist for this engine: 8140.27 and 8140.47, and they do not correspond to the same gearboxes.

Why the engine code is the essential starting point

The 8140.27 and the 8140.47 share the same engine capacity and the same turbodiesel architecture, but their crankshaft outputs and gearbox couplings differ. Mixing up the two reference families — which include references as different as 20KM20, 20KM81, or 9607213510 — leads to a fitment incompatibility. The year of manufacture alone is not sufficient: it is the engine code stamped on the block that determines the correct reference.

Key points to watch on this gearbox generation

On Ducato 2.5 TD vehicles used under heavy load or in intensive commercial use, wear to the 2nd gear synchroniser and play at the gearbox output are the most frequently reported symptoms. Gearboxes from this generation, produced up to 2002, are available in two ways: reconditioning of your own unit, or exchange from existing stock — the choice depends on the condition of the casing and the availability of the reference in question.
