Neutral (See Transmission Gear Identification, Neutral Position Figure)

The referenced figure is a schematic view of the 5-speed transmission in neutral position. Motion from the engine is transferred through the clutch, to the input shaft. The gear on the input shaft transfers the motion to the countershaft. Each gear on the countershaft transfers motion to its mating gear on the main shaft.

Each pair of mating gears (first/second and third/fourth) on the main shaft share a sleeve that is keyed to and turns with the main shaft. Between the sleeve and each gear is a synchro used to synchronize sleeve and gear speeds for easy engagement. Each sleeve has inner teeth that engage with crown teeth machined on the forward gears. In neutral position, all three sleeves are disengaged from the forward or reverse gears. With no sleeves engaged, all gears are free wheeling. Only the reverse sliding gear does not turn.
