Tremec TR-6060 transmission

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 (810 N·m) of torque.

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:

Recommended Oil

General Motors uses Texaco ATF Type III 1863 fluid and is certified "fill-for-life," requiring no fluid changes.[2] 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.
