Jaguar Transmissions - General Information

The gearbox fitted to the Jaguar Mk VII, VIII and Jaguar IX plus the Jaguar Mk I and Mk II saloons is known as the Moss Box. Reverse is located to the left and up. There is no synchromesh on first gear. We do not use this gearbox in the Suffolk SS100.

The gearbox fitted to the Mk X Jaguar 420, the later S Type saloons and all XJ6 cars is known as the Short Compact. Reverse is to the left and down. There is synchromesh on first gear. This is our first choice of gearbox for the Suffolk SS100 as it is very strong and also fitted with Laycock overdrive.

Late Series III Jaguar XJ6 cars were fitted with a 5 speed gearbox that was originally designed for the Rover SD1. This option is available as an alternative gearbox for the SS100.

The vast majority of Jaguar XJ6 cars were made with 3 speed automatic transmission. A number of the Suffolk SS100 cars have been fitted with this gearbox.

Some customers have fitted their cars with Getrag gearboxes and one car has a Borg-Warner T5 manual gearbox. We can advise you.

Final Drive - Differentials

All Suffolk SS100 cars are fitted with the Salisbury Jaguar final drive unit.
Usual ratios are 3.31:1 and 3.54:1. Other ratios are available.
Limited slip differentials are available at extra cost.
