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 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 (580 N⋅m) to 650 lb⋅ft (880 N⋅m) of torque, depending on gearing.^[1]

TREMEC sells the TR-6060 as the "Magnum" for aftermarket applications.
