Reconditioned Opel Astra Gearbox

Opel Astra Gearbox 2002 to 2023: from the Easytronic Automated Manual to the Widespread 6-Speed

Over twenty years of production, the Astra never offered a torque-converter automatic or a dual-clutch gearbox: the transmission is either a conventional manual or the Easytronic automated manual gearbox. The latter is available only on the 1.0 Turbo (engine codes B10XFL, B10XFT); all other engines are fitted exclusively with a manual gearbox. The key shift between generations is the move from five to six speeds: the naturally aspirated 1.4, the 2.2 (Z22SE, Z22YH) and the earliest versions of the 1.7 CDTi retain the 5-speed gearbox, whereas virtually all more recent or more powerful engines come with the 6-speed manual.

Petrol or diesel: gearbox families that don't mix

On the petrol side, the 1.4 Turbo (A14NEL, A14NET), the 1.6 Turbo (A16LER, A16LET, Z16LET), the 1.2 (D12XHT, F12SHT), the 1.2 Turbo (F12XHL, F12XHT) and the 2.0 Turbo (A20NFT, B20NFT, Z20LEH, Z20LER, Z20LET) all receive a 6-speed manual, but the gearboxes are not shared across these engines. Torque output and casing architecture differentiate the units: a gearbox from the 2.0 Turbo will not fit the 1.4 Turbo, even though both have six speeds.

On the diesel side, the 1.3 CDTi (A13DTE, Z13DTH) can be fitted with either a 5- or 6-speed manual depending on the year and specification, the 1.7 CDTi (A17DTE, A17DTR, Z17DTH, Z17DTL, Z17DTR) spans both gearbox generations, and the 1.9 CDTi (Z19DT, Z19DTH, Z19DTL) is invariably paired with the 6-speed manual. Here again, the engine code stamped on the block remains the only reliable identifier for determining which unit matches the vehicle — particularly on the 1.7 CDTi, where five codes coexist within the same engine capacity.

The Easytronic: a unique automated manual gearbox, sold without its actuator

The Easytronic gearbox on the 1.0 Turbo is an electro-hydraulically operated manual gearbox, not a conventional automatic in the strict sense. It is offered here without the robot unit or actuator, as this component is subject to a separate diagnosis and treatment. If the fault is located in the mechanical part of the gearbox, this solution is the right one; if the problem lies solely with the actuator, the mechanical gearbox itself is not at fault.
