Exam 71: Manual Transmission Fundamentals

An automatic transmission is used with a clutch.

When a vehicle is operated in high gear, the engine's crankshaft turns approximately three times to one turn of the transmission output shaft.

The effective diameter of the meshed gear (used for determining its circumference) is called the ____.

What is the difference between third gear and second gear?

What are the approximate transmission gear ratios for a three-speed transmission?

The synchronizer, or synchro, allows two gears spinning at different speeds to mesh without clashing.

Which of the following statements is LEAST-Likely true?

The term MOST-likely used to describe the clearance between meshing gear teeth is:

All of the following statements are true EXCEPT:

What is the relationship between backlash and helical gears?

The ____________________ is the distance from the center of a gear to its outside edge.

A(n) ____________________ allows the driver to adjust torque to fit an engine's operating requirements.

Most automatic transmissions achieve ____ with planetary gears and a lock-up torque converter.

All of the followings statements are true EXCEPT:

While having a discussion, Technician A says that the synchro allows two gears spinning at different speeds to mesh without clashing. Technician B says that it blocks the shift and equalizes the speed between two moving gears using cone clutch action. Who is correct?

The ____________________ is the ratio between the transmission output shaft and the differential ring gear.

What is the difference between first gear and reverse?

Briefly describe the power flow of high gear.

While having a discussion, Technician A says that twenty pounds of force applied to the end of a 1-foot rod produces 10 foot-pounds of torque. Technician B says that it produces 200 foot-pounds of torque. Who is correct?

Some trucks have a four-speed transmission with a very low first gear, sometimes called a(n) ____________________.
