Manual Transmission
The TR-6060 6-speed manual transmission features:
- six forward speeds and one reverse speed.
- forward gears are synchronized and helical cut.
- a reverse gear operates through a constant-mesh, fully synchronized system.
- a shift interlock system prevents the engagement of more than one gear.
- the countershaft is a one-piece design for added torque capacity.
- one tapered roller bearing on the rear of the output shaft and one cylindrical roller bearing on the front of the output shaft.
- two tapered roller bearings on the countershaft.
- a tapered roller bearing on the front of the input shaft and a axial thrust bearing on the rear of the input shaft.
- a tapered roller bearing on the countershaft extension.
- countershaft cluster endplay controlled by shims located in the transmission clutch housing.
- input/output shaft endplay is controlled by shims located in the transmission clutch housing.
- removable wear pads on the shift forks.
- an aluminum main case, extension housing and clutch housing.
- a oil pump in the clutch housing for fluid cooling.
The transmission function is to move the vehicle from a rest position to motion. This is done by transferring the engine torque, through the transmission, to the vehicle rear wheels. The transmission input shaft receives power when the clutch is engaged. Torque flows through the input shaft to the drive gear. The torque travels downward to the countershaft drive gear and is delivered along the countershaft to all the countershaft gears. The torque is then transferred upward to the engaged mainshaft gear. The transmission uses a system of mainshaft gears to change the speed and torque relationship between the engine crankshaft and the transmission output shaft.
Transmission Identification
The transmission identification tag is located under the lower bolt that retains the extension housing to the main case.
The 6 speed (TR-6060) transmission is available for the Mustang Shelby GT500 5.8L (4V).
