Exam 10: Common Automatic Transmissions

The W5A330 used in the Chrysler Crossfire is a version of the NAG1 transmission designed by Mercedes-Benz.

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

The ____________________ controls fluid flow and exhaust in the accumulator circuit according to PCS operation.

The GM 4R70 is a four-speed automatic transmission that uses a Ravigneaux compound planetary gear set.

A(n)____________________ provides controlled pressure to the reverse boost valve, accumulator valve, and the torque signal compensator valve.

The ____________________ controls line pressure in the system.

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?

The ____________________ controls TCC apply and release according to the position of the TCC regulator valve and the PWM solenoid.

The ____________________ is mechanically linked to the shift selector linkage. It directs line pressure to the appropriate passages for clutch and servo operation by opening and closing feed passages.

When considering GM transmissions/transaxles, the major difference in the design of the 4L60-E and the 4L65-E is the number of planetary pinion gears. 4L60s have ____________________ pinion gears and the 4L65s have ____________________ pinion gears.

The Chrysler collision detection system (CCD)is a means for the driver to avoid vehicle collisions.

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?

Technician A says most transmission solenoids must be removed as an assembly. Technician B says the clutch housing is the mounting place for most transmission solenoids. Who is correct?

____________________ are simple on and off solenoids that control upshifts and downshifts in all forward gear ranges.

The Ford AOD was the first automatic transmission to have a built-in overdrive.

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?

Technician A says the BMW 6HP26 is a five-speed unit that is based on the Simpson gear set design. Technician B says this transmission is unique in that it has a very high torque capacity and is smaller and lighter than comparable units. Who is correct?

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

Explain what is used in Honda transaxles to provide different gear ranges.

Technician A says before assembling a transaxle, the seals and bearings should be lubricated with clean bearing grease. Technician B says when reassembling a transaxle, seals can be reused if they are not damaged. Who is correct?
