"The JD Sport five-speed transmission has been designed in-house for the classic Jaguar range, or other marques that use similar transmissions. With a power rating of 400bhp, it will be equally at home on either the road or track in a Jaguar E-type or Mk2, and any Jaguar XK. Dimensionally the same as a 4.2 all-synchromesh unit, the JD Sport five-speed transmission is actually lighter than any period factory unit. It uses a reinforced aluminium casting, and all-synchromesh helical cut gears."

Roy,
Have you any idea of the comparative costs with the Tremec 5 box?

Reg,

POA, but I imagine that, with the amount of design work that has gone into its' construction plus the JD Classics name, it will be quite an expensive item.
