Hi all
can anybody tell me what gearbox i could put in my Vectra C 1.8cc it has the F17 at the moment just wondering if any others will fit

think only a F17 will do I replaced mine with a CR (close ratio ) , it had a WR wide ratio before .
the CR is from an SRI / sport engine variant .
others might physically fit but will cause problems .
