Exam 38: Manual Transmissions and Transaxles

A transmission or transaxle uses meshed gears of various sizes to give the engine a mechanical advantage over its driving wheels.

A 1:1 ratio is called ____________________ drive.

A __________ transaxle has differential gears that change the direction of power flow 90 degrees.

The VSS [vehicle speed sensor] provides information for the ______.

When a small gear drives a larger gear, the output speed _____.

What does the term "constant mesh" mean?

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?

Technician A says an overdrive gear ratio is less than 1 to 1. Technician B says overdrive ratios provide more torque than underdrive ratios. Who is correct?

Technician A says lower gears provide lower vehicle speeds but more torque. Technician B says higher gears provide less torque but higher vehicle speeds. Who is correct?

Technician A says in a conventional transmission, the speed gears freewheel around the mainshaft until they are locked to it by the synchronizer. Technician B says when not engaged, speed gears slide away from the counter gears until they are no longer in mesh. Who is correct?

The reverse lockout system prevents shifting the transmission into reverse when the vehicle speed exceeds ______ mph.

Blocking rings are usually made from aluminum and are part of a typical synchronizer assembly.

How is a gear pitch calculated?

Transmission shafts are mounted ____________________ to one another.

Which of the following is NOT one of the basic manual transmission shafts?

Explain the relationship between output speed and torque.

There can be no power output until one of the speed gears is locked to the ___________________.

Technician A says helical cut gears have teeth cut at a 90-degree angle to the side of the gear. Technician B says helical gears run without creating gear whine. Who is correct?

Two meshed external-cut gears turn in opposite rotations.

Which of the following is NOT a function of gears?
