Gearbox

​

3000M

Ford 4 Speed Gearbox as standard. Pretty strong reliable gearbox, cast iron casing & bellhousing. Layshaft wear evident after year of use but generally last well.

​

A 5 Speed gearbox conversion is a favourite for the 3000M (Ford Sierra), as are overdrive options. The Reliant Scimitar GTE had an overdrive gearbox fitted & so many second hand boxes complete or for spares are still available. As the Ford Gearboxes generally had the same gear casing bolt pattern, adapting other (better) Ford gearboxes has been possible, including the Cosworth Gearbox. For the 5 speed mod you'll need to shorten the propshaft nose by a small amount. More details to follow on this.
