Which type of gear develops the problem of gear whine at higher speeds?

Describe the purpose of an upshift lamp.

Four-wheel drive vehicles typically use a transmission and ____________________ case to deliver power to all four wheels.

A transaxle whose differential gears change the direction of power flow 90 degrees is called a ___________________ transaxle.

Technician A says the counter gear is actually several gears machined out of a single piece of steel. Technician B says the counter gear is driven by the clutch (main drive/input) gear and drives the mainshaft speed gears. Who is correct?
