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.
It is manufactured by Transmission Technologies
Corporation and is rated for 600 ft·lbf (810 N·m) of
torque.

5. overwiew
The TR-6060 contains removable wear pads on the shift
forks.
uses aluminum alloys for the main case, extension
housing, and clutch housing.
As usual, the forward helical cut gears are synchronized
however, the reverse gear operates through a fully
synchronized constant-mesh system.

8. upgrades from T56-six speed
Reduced friction in the shifter system by
adding new cams and no-friction plungers.
Forward and rearward shift detent grooves
are broached on the front of the main-shaft
with a spring-loaded anti-friction roller, for
more precision control of shift detents and
positive shift feel.

9. upgrades from T56-six speed
Anti-friction balls and fine-pitch splines on all
synchronizers 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
increase transmitted torque.
