___________ occurs when two gears of equal size turn without changing torque or speed.

If the driving gear is smaller than the driven gear, torque increases.

The main (or output) shaft turns the same speed as the input shaft in what gear?

The pinion gears walk forward on the __________ turning side gear.

The _______________reduces the speed of all shafts to engage the 1-2 synchronizer to the first speed gear.

Explain how the gear ratio relates to the number of teeth of the driving and driven gears.
