This modification completely transforms the performance especially at cruising speeds when the fifth gear allows a reduction of around 1200 rpm giving a greater economy and far less stress on both the car and driver!
It uses a Ford Sierra Type 9 gearbox as used on 1.6L and 1.8L (1982-91) and 2.0L (1982-87). The gearbox is not part of the kit, but we can supply a guaranteed unit, or a sound unit can often be obtained cheaply from a vehicle dismantler.
