Moss Classic Jaguar is proud to distribute the best five-speed conversions available. Theyre based on the tried-and-true 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 The Moss box was basically out of date in the mid fifties; it was woefully obsolete by the mid sixties and certainly not up to the standards of Jaguar engines or suspensions.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. The following conversion kits are available. XK-120: A modified original bellhousing is used to mount this transmission in an XK-120 and retain the standard shifter location. Kit includes new transmission (not rebuilt), speedometer cable, shift lever, shift knob, clutch disc and drive shaft adapter yoke. The stock mechanical clutch mechanism, pressure plate and throw-out bearing are retained (replacing the pressure plate and throw-out bearing would be prudent, however). A new drive shaft must be fabricated. The standard gearbox supplied with this kit has the following first-through-fifth ratios: 2.95, 1.94, 1.34, 1.00 and .73. You must send your bell housing for modification.

Moss Classic Jaguar Remanufactured Parts Policy

Remanufactured parts carry a core charge. This is a deposit that will be refunded once we receive your old part back and deem it a viable and rebuildable dirty core. The sooner you send the dirty core back, the sooner your deposit will be refunded.

Here is the fine print as it relates to remanufactured parts and core charge refunds.

  • Dirty cores must be an exact match for the part purchased. A Chevy water pump will not suffice for a Jaguar V-12 unit and an XJ-6 wiper motor cannot be accepted for an XK-120 part. In some limited cases we will accept non-matching cores for a reduced refund. Please call first.
  • Your dirty core must be complete. If we supplied your remanufactured water pump with a pulley, for instance, your dirty core must have a pulley as well. There are some gray areas here, as most remanufactured water pumps, for example, are not supplied with various hose fittings. These may be removed from your dirty core and fitted to the purchased remanufactured part. Same goes for some remanufactured brake master cylinders - there are fittings that may not be supplied with the remanufactured part. Bottom line: check the purchased part against your dirty core and call 800-444-5247 if you have any questions. The core must be assembled, a box of loose parts in not acceptable. An incomplete dirty core will result in a reduced core deposit refund, or rejection of the dirty core entirely.
  • Your dirty core must not be damaged. Generators cannot have broken ears; steering racks cannot be shaped like bananas; wiper motors cannot be fire-roasted, etc.
  • Your dirty core must be rebuildable or no core refund will be issued.
  • When shipping your dirty core to us, please ensure it is packed well. Use our original packing methods as a guide. It is your responsibility to ensure the dirty core is packed well enough to arrive at Moss Classic Jaguar undamaged.
  • Cores must be returned in the original box. You may need to enclose the original box inside another box to ensure safe transit.
  • Please completely drain all fluids from your dirty core.
  • Please enclose a copy of your invoice with the dirty core. This will ensure a speedy core charge refund. If we don't know who sent us the parcel, we cannot refund your deposit.
  • Please keep dirty core returns and other returns separate. This will ensure your core charge refund is not delayed.
  • Dirty core returns sent freight-collect will be refused.
