General

The T45 is a five-speed manual transmission containing the following features:
^ A fifth speed gear that functions as an overdrive gear.
^ The first gear through fourth gears are meshed within the case.
^ The reverse gear, fifth speed gear and synchronizer are located on the back of the case in the extension housing.
^ The first/second and third/fourth shift rail is mounted in the case.
^ The fifth-speed gear synchronizer and reverse gear train are shifted through a reverse gearshift lever, activated by a shift rail.
^ A shift interlock system, located in the case, prevents engagement of more than one gear.
^ The shift detent is located in the extension housing turret. It consists of a detent plate, gearshift offset lever, detent spring and detent ball.
^ All gears are helical-cut for smooth, crisp shifts and quiet operation.
^ All forward gears are synchronized. Reverse operates through a constant-mesh-double disconnect system.





^ The floor-mounted gearshift lever operates a main shift control shaft which extends from the extension housing into the case.
