Question 1

Technician A says the Chrysler 545RFE is a six-speed transmission. Technician B says that the 545RFE is equipped with two ATF filters, an external canister-type filter, and an oil sump filter. Who is correct?
A)A only
B)B only
C)Both A and B

A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Both technicians are correct. The Ford 4R70E and 4R75E are considered to be wide ratio geartrain transmissions, and the latest model of Ford is a nine-speed transaxle called the 948TE.

Question 4

Technician A says that all transmissions have a ATF dipstick and filler tube. Technician B says that some transmissions are equipped with an ATF warmer. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Not all transmissions have an ATF dipstick and filler tube; many modern vehicles have sealed transmissions without a dipstick for the user to check fluid levels. However, some transmissions are indeed equipped with an ATF warmer to help maintain optimal fluid temperature.

Question 5

Technician A says that a solenoid that is controlled by a computer is switched on or off on the ground side of the circuit. Technician B says a Chrysler-built unit, when operating in "limp-in" mode, will allow operation in all gear ranges but at reduced efficiency. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is correct because it is common for computer-controlled solenoids, including those in automotive applications, to be switched on the ground side of the circuit. This allows the computer to control the solenoid by completing or interrupting the circuit to ground. Technician B is incorrect because when a Chrysler-built unit operates in "limp-in" mode, it typically restricts the transmission to operate in only one gear (often second gear) to allow the vehicle to be driven to a repair facility, not in all gear ranges.

B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is correct that the Mercedes-Benz 7G-Tronic was indeed the first seven-speed automatic transmission. Technician B is also correct that this unit allows the electronic control unit to "skip" gears when upshifting or downshifting. Therefore, both technicians are correct.

Question 9

Technician A says that the RFE Series uses seven control devices. Technician B says that the RFE Series uses seven solenoids and five pressure switches. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

The RFE Series indeed uses seven solenoids for control, but it also incorporates five pressure switches as part of its control devices, making both Technician A and Technician B correct in their statements.

A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Both technicians are correct. Selective thrust washers and snap rings can be used to correct end play in certain applications.

Question 11

Technician A says the AX4N  is a nonsynchronous type transaxle. Technician B says in an AX4N transaxle, the intermediate band was eliminated. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is correct that the AX4N is a nonsynchronous type transaxle. However, Technician B is incorrect because the intermediate band is not eliminated in the AX4N transaxle.

Question 12

Technician A says the output member of the gear set can be the ring gear. Technician B says the output member of the gear set can be the front planetary carrier. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Both technicians are correct. In a planetary gear set, either the ring gear or the front planetary carrier can serve as the output member, depending on which gear is fixed and which gear rotates.

Question 13

Which of the following is not true of a Ford 5R55E transmission?
A)An additional gearset was added to achieve the fifth gear.
B)It is an updated version of the A4LD
C)It uses additional control devices for 5th gear.
D)None of the above are correct.

Accepted Answer

The 5R55E transmission is an updated version of the A4LD transmission, and it uses an additional gearset to achieve the fifth gear. It also uses additional control devices for 5th gear.

Question 14

Technician A says the 4R44E is a rear-wheel-drive transmission. Technician B says the 4L65-E is also a rear-wheel-drive transmission. Who is correct?

A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

The BMW 6HP26 is a six-speed automatic transmission, not a five-speed, and it is known for its high torque capacity and compact, lightweight design compared to other transmissions.

Question 17

Which of the following is not true of a Ravigneaux geartrain?
A)Planetary pinion gears rotate on shafts.
B)It has two large sun gears.
C)A single ring gear surrounds the complete assembly.
D)It uses two sets of planetary pinion gears.

Accepted Answer

A Ravigneaux geartrain has one sun gear and one ring gear, but it uses two sets of planetary pinion gears to achieve its gear reduction. Therefore, option B is not true as it states that a Ravigneaux geartrain has two large sun gears.

Question 18

​Technician A says Chrysler's 68RFE is a three-speed unit with a high torque rating for RWD vehicles and is fully electronically controlled. Technician B says Chrysler has used transmissions and transaxles with planetary gears in tandem built by Mitsubishi and Mercedes. Who is correct?
A)​A only
B)​B only
C)​Both A and B
D)​Neither A nor B

Accepted Answer

Technician A is incorrect because the 68RFE transmission is actually a six-speed unit, not a three-speed. Technician B is correct that Chrysler has used transmissions with planetary gears in tandem built by Mitsubishi and Mercedes.

Question 19

Which of the following is not true of a Simpson geartrain?
A)It contains two ring gears.
B)It uses two separate planetary gear sets.
C)It uses a common sun gear.
D)It uses a common planetary pinion carrier.

Accepted Answer

A Simpson geartrain does not use a common planetary pinion carrier; it uses a common sun gear and two planetary gear sets.

Question 20

Technician A says before installing friction discs, they should be soaked in clean ATF. Technician B says when assembling a transmission, the steel clutch plates should be coated with petroleum jelly. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Before installing friction discs, they should be soaked in clean ATF to soften them and improve their performance. However, coating steel clutch plates with petroleum jelly may cause them to slip instead of engaging properly, which could lead to transmission failure. Therefore, technician B is not correct.
