Reconditioned Opel Meriva 1.7 CDTi Gearbox

On the Meriva 1.7 CDTi, the 5-speed gearbox came before the 6-speed: two distinct transmissions across fourteen years of production

The 1.7 CDTi in the Meriva spans the period 2003–2017, but the engine underwent significant changes. The early years (Meriva A) are associated with engine codes Z17DTH and Z17DTR, which are paired with a 5-speed manual gearbox. The transition to the Meriva B brought in engine codes A17DTC and A17DTS, paired with a 6-speed manual gearbox. This change in ratio count is significant: the two families are not interchangeable, and mixing up the generations is the most common mistake when searching for a part.

Identify your gearbox precisely before taking any further steps

The engine code, visible on the manufacturer's plate or in the vehicle's documentation, is the only reliable criterion for determining which transmission is actually fitted to the vehicle. The year alone is not sufficient: production overlaps exist around the key changeover dates. The references listed here — including Getrag gearboxes referenced AWJ, QG and 7K — correspond to these two distinct families, 5- or 6-speed depending on the engine code in question.
