Description

Our five speed kits are based on the tried and true Tremec (formerly Borg-Warner) T-5 unit, but are hand-assembled with many custom components for each Jaguar application. Why install a five speed. First, as far as feel and ease of use are concerned, these gearboxes are worlds apart from the original Moss (aka non-synchro) gearboxes, which are pleasingly vintage but rough and slow. The Moss box was basically out of date in the mid fifties; it was woefully obsolete by the mid sixties and certainly not up to the standards of Jaguar engines or suspensions. Our five-speeds bring the transmission up to modern standards and eliminate whats arguably the most anachronistic feature of early Jaguars. Second, many internal components are no longer available for Jaguar gearboxes (even the later, all-synchro, units), so a five-speed is sometimes the only alternative to a terminally-ill standard box. Third, with a five speed, you obviously gain another gear, making for excellent 1-4 ratios and an overdrive fifth for more relaxed cruising at highway speeds.

Kits include new transmission (not rebuilt), adaptor plate, shift lever position adaptor, speedo cable adaptor (standard speedo cable retained), mounting kit and clutch disc. Standard ratios are 2.95, 1.94, 1.34, 1.00, 0.63. A .80 fifth gear is available at extra cost. Driveshaft is not included -- have a local shop modify your original or make a new unit. This kit is for manual transmission conversions only. It does not include parts to convert from an automatic transmission. Photo might not represent current kit contents. For XK-120, a notch must be cut in the frame crossmember to accommodate the rear transmission mount. This requires a small amount of welding.
