Exam 20: Dual Clutch Transmissions

Tech A states that dual clutch transmissions and dual clutch manual transmissions are the same. Tech B states that dual clutch transmissions are different from dual clutch manual transmissions. Who is correct?

The dual clutch system contains a set of damper springs. Technician A says that these springs help reduce shift shock as the clutch is applied. Technician B says that the springs help absorb engine pulses while driving the vehicle. Who is correct?

A __________ contains two sets of single disc clutches, similar to a traditional manual transmission clutch disc.

In a dual clutch system, one clutch drives the even numbered gears while the other clutch drives the odd numbered gears.

Tech A states that on a dual clutch transmission one or more of the synchronizers must be engaged in order for the parking pawl to engage. Tech B states that both clutches are applied to park the vehicle. Who is correct?

Most FWD applications use a nested clutch design as it is shorter in length.

Choose the correct statement with respect to the construction of a dry clutch system.

Tech A states that dual clutch transmissions are actually more like a manual transmission than a traditional automatic. Tech B states that rebuilding a dual clutch transmission requires the same tools as rebuilding a manual transmission. Who is correct?

Which of the following should be done after installing the clutch release bearing assembly into the case?

Technician A says that dual clutch systems contain a set of damper springs to absorb engine pulses while the vehicle is driving. Technician B says that the damper springs help reduce damaging shift shock as the clutch is applied. Who is correct?

Tech A states that after replacing a clutch in a dual clutch vehicle the technician should take the vehicle on an extended test drive (a few miles). Tech B states that all adaptives must be performed before test driving the vehicle. Who is correct?

Tech A states that when replacing a dual clutch an entire replacement kit should be purchased that includes necessary seals, actuators, etc. Tech B states that the clutches can be purchased individually so you can replace a single clutch only. Who is correct?

A dry clutch system is operated by:

When a dual clutch transmission is in reverse, power flows through input shaft #1.

Which of the following statements regarding a dry clutch system is NOT true?

A wet clutch is operated by:

Technician A says that there are two output shafts in a dual clutch transmission. Technician B says that there is a center main shaft that is actually both input shafts. Who is correct?

Technician A says that a dual clutch transmission has improved fuel economy. Technician B says that the dual clutches are each connected to a separate input shaft that drives its own set of gears. Who is correct?

In a wet clutch system, which of the following directs the flow of hydraulic oil?

Technician A says that when a transmission is in first gear, the first input shaft (or the hollow shaft) is connected to the engine. Technician B says that when the transmission is in second gear, the first input shaft (or the hollow shaft) is connected to the engine. Who is correct?
