Question 1

Technician A says by using selective thrust washers, end play is often corrected. Technician B says by using selective snap rings, end play is often corrected. Who is correct?

Accepted Answer

Both technicians are correct. Selective thrust washers or selective snap rings can be used to adjust end play in certain types of engines.

Question 2

Technician A says in most transmissions, the oil pump is bolted to the transmission case. Technician B says in some transmissions, the oil pump is press-fitted into the case. Who is correct?

Accepted Answer

The answer of Technician A says in most transmissions, the...

Question 3

Technician A says the Torqueflite transmission was the first to use the Simpson compound planetary gear set. Technician B says the first modern style 3-speed transmission to use a torque converter was the Torqueflite transmission. Who is correct?

Accepted Answer

The Torqueflite transmission was indeed the first to use the Simpson compound planetary gear set and was also the first modern style 3-speed transmission to use a torque converter.

Question 4

Technician A says Ford offered the first automatic transmission with a built-in overdrive when they introduced the AOD. Technician B says the C-6 was replaced by the AOD in both cars and trucks. Who is correct?

Accepted Answer

The answer of Technician A says Ford offered the first...

Question 5

Technician A says in a Torqueflite transmission, the apply device is the one-way overrunning clutch. Technician B says in a Torqueflite transmission, the front and rear bands are the holding devices. Who is correct?

Accepted Answer

In a Torqueflite transmission, the front and rear bands are indeed the holding devices, as Technician B states. The one-way overrunning clutch is not the apply device, so Technician A is incorrect.

Question 6

Technician A says a variable displacement rotor-type oil pump is used in a 4L60 transmission. Technician B says a variable displacement vane-type oil pump is used in a 3L30 transmission. Who is correct?

Accepted Answer

Technician B is correct. The 3L30 transmission uses a variable displacement vane-type oil pump, but the 4L60 transmission uses a fixed displacement vane-type oil pump.

Question 7

Which of the following is true of an 4R70E transmission?

Accepted Answer

The 4R70E transmission has two bands and two one-way clutches.

Question 8

Some automatic transmissions use which of the following to achieve different gear ratios?

Accepted Answer

Automatic transmissions can use a combination of tandem planetary gear sets, Ravigneaux gear sets, and helical gear sets to achieve different gear ratios. Therefore, the best choice is D, All of the above.

Question 9

Which of the following is not true of a Simpson geartrain?

Accepted Answer

The answer of Which of the following is not true...

Question 10

Technician A says a Chrysler 36RH is a transaxle. Technician B says a Chrysler 31TH is a transaxle. Who is correct?

Accepted Answer

The answer of Technician A says a Chrysler 36RH is...

Question 11

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?

Accepted Answer

Both technicians are correct. The output member of the gear set can be either the ring gear or the front planetary carrier, depending on the specific design of the transmission.

Question 12

Technician A says Torqueflite-based transaxles have the same basic parts as an A-904 transmission as well as additional parts. Technician B says Torqueflite-based transaxles used in FWD vehicles have little in common with other transaxles. Who is correct?

Accepted Answer

Torqueflite-based transaxles share basic components with the A-904 transmission but include additional parts specific to their design. Technician B's statement is incorrect as Torqueflite-based transaxles share common features with other transaxles.

Question 13

Some rear clutches use which of the following to multiply the applying force of the piston?

Accepted Answer

Belleville springs are used in some rear clutches to multiply the applying force of the piston, enhancing the clutch's ability to transmit torque.

Question 14

Which of the following is not true of a Ford 5R55E transmission?

Accepted Answer

The answer of Which of the following is not true...

Question 15

Which of the following is not true of a Ravigneaux geartrain?

Accepted Answer

A Ravigneaux geartrain only has one sun gear, not two.

Question 16

Which of the following is provided by the Torqueflite transmissions and transaxles?

Accepted Answer

Torqueflite transmissions and transaxles typically provide three forward gears and one reverse gear ratio.

Question 17

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?

Accepted Answer

Technician A is correct that friction discs should be soaked in clean ATF before installation. This helps to lubricate and prevent damage to the friction material during initial engagement. Technician B is not correct as coating steel clutch plates with petroleum jelly can cause clutch slippage and should not be done.

Question 18

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?

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 19

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?

Accepted Answer

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

Question 20

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?

Accepted Answer

Both technicians are correct. The 4R44E is a rear-wheel-drive transmission commonly used in Ford vehicles, and the 4L65-E is also a rear-wheel-drive transmission commonly used in General Motors vehicles.
