Reconditioned Ford Fiesta Gearbox

Ford Fiesta 2001–2017: a 100% manual transmission range, but five and six speeds are not interchangeable depending on the engine

Across the entire 2001–2017 range, the Fiesta never came with an automatic, automated manual or dual-clutch gearbox as standard: the transmission is exclusively manual, in either five or six speeds depending on the engine. That settles the question of gearbox type straight away — but it shifts the real identification challenge to matching the engine code stamped on the block, the engine capacity and the number of speeds precisely. The same commercial designation can cover different gearboxes.

Petrol: from the 1.2 naturally aspirated to the 1.6 EcoBoost — distinct gearbox families

Petrol engines span a wide spectrum. The 1.2 (codes FUJA, FUJB, SNJA, SNJB), 1.25, 1.3 (A9JA, A9JB) and 1.1 (XYJD) all receive a 5-speed manual gearbox, but their internal ratios and couplings differ: a gearbox from a 1.25 is not a mechanical replacement for one from a 1.2 with code SNJA. The 1.0 EcoBoost (codes M1JA, M1JE, SFJA, SFJB) is the only 3-cylinder petrol engine in the range; it can be fitted with either a 5-speed or a 6-speed manual depending on the year and power output — checking the code is essential before placing any order. The 1.6 EcoBoost (JTJA, JTJB) and the 2.0 (N4JA, N4JB) each pair with a specific gearbox: 6-speed for the former, 5-speed for the latter.

Diesel: 1.4, 1.6 and 1.5 TDCi — the IB5 designation as a key point to watch

On the diesel side, three families coexist. The 1.4 TDCi (F6JA, F6JB, F6JD) and the 1.6 TDCi (HHJA, HHJB, TZJA / TZJB / T3JA) are both 5-speed units, but the 1.6 TDCi can be fitted with an IB5 gearbox, a variant that must be identified separately from the standard 5-speed manual — the two are not interchangeable when fitting. The 1.5 TDCi (XVJA, XVJB, XVJC) moves to 6 speeds, making it the only 6-speed diesel gearbox in the range. This change in ratio count accompanied the introduction of this engine in the final years of the Fiesta Mk7, and the corresponding gearbox is dimensionally different from the earlier 5-speed diesel units.
