Chap 127

How much is engine torque increased or multiplied when a typical torque converter is at stall speed? A) Double B) Ten times C) Eight times D) Four times

A) Double

Technician A says that five-speed automatic transmission will often use a compound planetary gear set. Technician B says that the torque converter clutch is often pulsed on and off to provide smooth engagement. Which technician is correct?

Both Technicians A and B

Technician A says that one planetary gear set can provide gear reduction, overdrive, and reverse. Technician B says that most transmissions today use compound (multiple) planetary gear sets. Which technician is correct?

Both Technicians A and B

Using A torque converter smaller than stock size could result in ___________. A) Faster than normal acceleration B) Both, Faster than normal acceleration and Reduced fuel economy. C) Reduced fuel economy D) Slower than normal acceleration

B) Both, Faster than normal acceleration and Reduced fuel economy.

Technician A says that when an automatic transmission/transaxle shifts into overdrive, the output shaft is rotating faster (higher RPM) than the engine crankshaft. Technician B says that an overdrive ratio is a ratio where the first number is less than 1. Which technician is correct?

Both Technicians A and B

Technician A says that a held member is also called the reaction member. Technician B says that if any two elements are locked together, then the output will be 1:1. Which technician is correct?

Both Techs A and B

Which compound planetary gear set is commonly used in six-speed transmissions? A) Ravigneaux gear set B) Simpson gear set C) Lapelletier gear set D) Simple gear set

C) Lapelletier gear set

Two technicians are discussing automatic transmissions/ transaxles. Technician A says that it is normal for a vehicle to move slightly when the gear selector is in the "drive" position with the brakes released. Technician B says that the stator may be defective if the vehicle moves while in gear when the engine is at idle speed. Which technician is correct?

Technician A only

Technician A says that all dual clutch automatic transmissions use two dry clutches. Technician B says that some automatic transmissions do not use planetary gear sets. Which technician is correct?

Technician B only

Which compound gear set uses a planetary gear set in front of a Ravigneaux gear set? a)Ravigneaux gear set b)Simple gear set c)Lapelletier gear set d)Simpson gear set

c)Lapelletier gear set
