Question 1

What is the primary function of a torque converter in an automatic transmission?

Accepted Answer

Transfer engine torque to the transmission while allowing slip at low speeds

Answer

A torque converter uses fluid coupling to transfer engine torque to the transmission, allowing the engine to idle while the vehicle is stationary.

Question 2

Which component in a manual transmission prevents gear clash during shifting?

Accepted Answer

Synchronizer ring

Answer

Synchronizer rings (synchros) match the rotational speeds of the gear and shaft before engagement, preventing grinding or clashing.

Question 3

A vehicle with a front-wheel-drive layout uses which type of joint to handle both drive and steering angles?

Accepted Answer

Constant velocity (CV) joint

Answer

CV joints maintain constant rotational speed regardless of joint angle, making them essential for FWD vehicles that must steer and drive simultaneously.

Question 4

What does a limited-slip differential (LSD) do compared to an open differential?

Accepted Answer

Distributes more torque to the wheel with greater traction

Answer

An LSD uses clutch packs or other mechanisms to bias torque toward the wheel with better traction, improving performance over an open differential.

Question 5

In a rear-wheel-drive vehicle, the driveshaft connects the transmission output to which component?

Accepted Answer

Rear axle differential

Answer

In a RWD layout, the driveshaft transmits torque from the transmission to the rear axle differential, which then splits power to the rear wheels.
