Tremec TR-6060 transmission
Tr6060 transmission shifter conversion kit

The Tremec TR-6060 six-speed manual transmission features six forward speeds and one reverse speed. It is derived from the Tremec T-56 6-speed manual transmission. As usual, the forward helical cut gears are synchronized however, the reverse gear operates through a fully synchronized constant-mesh system. The TR-6060 contains removable wear pads on the shift forks, and uses aluminum alloys for the main case, extension housing, and clutch housing. It is manufactured by TREMEC (formerly Transmission Technologies Corporation) and is rated for 600 lb⋅ft (810 N⋅m) of torque.

Changes from T56-six speed[edit]

The FG Falcon launch documentation describes the new gearbox: 'The new synchroniser package features triple synchromesh on first and second gears, and double synchromesh on all other gears, including reverse, which has significantly reduced gear shift efforts and shift travel.

The reduced shift travel provided by the synchroniser package has also allowed increased space for the use of larger gears, which are stronger to deliver improved torque capacity and gearbox durability. A new single-piece counter shaft also contributes to the greater torque capacity and durability enhancements.

Other features of the new TR-6060 transmission include:

  • Reduced friction in the shifter system courtesy of a new cam and anti-friction plunger to control the side load shift detents.
  • Forward and rearward shift detent grooves are broached on the front of the main-shaft with a spring-loaded anti-friction roller, for more precise control of shift detents and positive shift feel.
  • Anti-friction ball struts, sintered hubs and fine-pitch splines on all synchronisers for reduced friction between components - delivering improved shift feel and reduced shift efforts.
  • Wider, two piece gears with machined clutch teeth for more precise gear engagement and reduced potential for gear block-outs.'
