The 1-2 synchronizer sleeve moves forward to 
gage the clutch teeth on the first-speed gear. The
power coming in the input shaft goes through the
first-speed gear and into the synchronizer sleeve.

The sleeve turns the synchronizer hub and output
shaft. The output shaft pinion gear turns the differen-
