Tremec TR-6060 transmission
Encyclopedia
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 per 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 Transmission Technologies Corporation
and is rated for 600 ft.lbf of torque.

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 TR6060 transmission include:
Ford US lists a fill specification of 3.65 quarts of Mercon-V automatic transmission fluid.
There is speculation that the use of thicker manual transmission oil can reduce the characteristic rattle noise on idle and during low revolutions under load - however, the use of such fluids would likely void any warranty.
Borg-Warner T-56
The T-56 six speed manual transmission has been used in a wide range of vehicles from General Motors, Dodge, and Ford Motor Company. The transmission was originally designed and built by Borg-Warner for the Dodge Viper later being used by GM in 1992 for the generation II and later engines, but as...

Changes from T56-six speed
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 TR6060 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."
Recommended Oil
General Motors uses Texaco ATF Type III 1863 fluid and is certified "fill-for-life," requiring no fluid changes.Ford US lists a fill specification of 3.65 quarts of Mercon-V automatic transmission fluid.
There is speculation that the use of thicker manual transmission oil can reduce the characteristic rattle noise on idle and during low revolutions under load - however, the use of such fluids would likely void any warranty.
