Exam 38: Manual Transmissions and Transaxles

When fourth gear is selected on a five-speed manual transmission, the synchronizer couples the ______.

The shifter fork engages a groove in the synchronizer ___________________.

When a small gear is meshed with a much larger gear, the input gear is often called a ___________________ gear, regardless of its tooth design.

The synchronizer ____________________ is precisely machined to slide onto the clutch hub smoothly.

Shift linkages are being discussed. Technician A says cables are used to connect the shift lever to the transmission. Technician B says rods are used to connect the shift lever to the transmission. 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?

When a large gear drives a smaller gear, the output speed _____.

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

Technician A says the transmission allows the driven wheels to spin faster than the engine. Technician B says the transmission multiplies the torque produced by the engine. Who is correct?

A(n) _____ gear is used to transfer motion without changing rotational direction.

A 2.85:1 ratio represents a gear ____________________.

How is a gear pitch calculated?

Most transaxles require a pilot bearing in the flywheel to support the input shaft.

What is the function of a synchronizer?

When the 1-2 shift rail is moved into first gear, the 3-4 and 5-R shift rails are prevented from moving by the ______.

Technician A says the main gears are also called speed gears. Technician B says speed gears freewheel around the mainshaft until they are locked to it by the engagement of their shift synchronizer unit. Who is correct?

Transaxles are commonly used on rear-wheel drive vehicles.

Gear ratios are being discussed. Technician A says higher gear ratios allow for higher vehicle speeds and more torque. Technician B says lower gear ratios provide less torque and reduce vehicle speed. Who is correct?

Describe shift blocking.

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