Reconditioned Hyundai Tucson Gearbox

Hyundai Tucson Gearbox: which one for 2004 to 2020, depending on your engine?

The answer comes down to two points: every engine listed here uses a 6-speed manual, but the internal references differ by engine code, and mixing up families can lead to ordering an incompatible part. The Tucson covered here spans three engines — the 1.7 CRDi, the 2.0 CRDi and the 1.6 petrol — across a range from 2004 to 2020, covering two generations of the model with distinct powertrains.

Diesel: 1.7 CRDi and 2.0 CRDi — two completely different gearbox families

The 1.7 CRDi (engine code D4FD) and the 2.0 CRDi cover two clearly distinct generations. The 2.0 CRDi from the early years (engine code D4EA, Tucson I from 2004) and the one from the following generation (engine code D4HA, Tucson III) do not share the same gearbox: the casings, shafts and manufacturer references all differ. Checking the engine code stamped on the block — not just the engine capacity — is the only way to avoid ordering the wrong part.

1.6 Petrol: G4FD or G4FJ — a distinction that matters

The 1.6 petrol comes in two engine codes listed in this collection: G4FD (naturally aspirated) and G4FJ (turbocharged, 1.6 T-GDi version). Despite sharing the same engine capacity, these two units take mechanically different gearboxes. The gearbox paired with the G4FJ handles a higher torque output; the two are not interchangeable. Two reconditioning options are available depending on the unit: exchange with a rebuilt unit, or rebuilding your own gearbox — the latter allowing you to retain your vehicle's original references.
