Will the f17 gearbox for the vectra b fit a vectra c?

The F17 gearbox from the Vectra B is not directly compatible with the Vectra C, as the two models have different engine configurations and mounting points. While some components may be similar, significant differences in design and electronics mean that a direct swap would likely require extensive modifications. It's always best to consult with a mechanic or specialist for specific compatibility and modifications needed.
