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 a double overdrive transmission. The TR-6060 is manufactured by TREMEC (formerly Transmission Technologies Corporation) and is rated for 430 lb.ft to 650 lb.ft of torque, depending on gearing. TREMEC sells the TR-6060 as the "Magnum" for aftermarket applications.

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 TR-6060 transmission include:

Lubrication

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. FCA Applications use Mopar ATF +4 Automatic Transmission Fluid.
