Exam 10: Common Automatic Transmissions

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?

Define the components of the Ravigneaux gear set.

​Most hybrids use a modified five-speed automatic transaxle .

​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?

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

The ____________________ , ____________________ , and the ____________________  control the amount of slippage the T/C will have.

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?

The ____________________ works with the accumulator valve to cushion the direct clutch application by absorbing some of the apply pressure.

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

Most GM transmissions use a rotor-type oil pump.

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?

​What is the purpose of a PCS (pressure control solenoid)?

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?

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?

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?

The ____________________ directs fluid flow according to shift solenoid operation, actuator feed pressure, and return spring force to control 1-2 and 2-1 shifts.

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?

The second clutch controls output through the 4T60 geartrain.

Describe the components used to provide various gear ratios in most GM transmissions using a Simpson geartrain.

Technician A says the Ford 4R70E and the 4R75E are considered to be wide ratio geartrain transmissions. Technician B says the latest model of Ford is a nine-speed transaxle called the 948TE. Who is correct?
