Chapter 38, Problem 7ASRQ
While discussing the power flow through a five-speed transmission while it is in first gear: Technician A says that power enters on the input shaft, which rotates the countershaft that is engaged with first gear. Technician B says that the first gear synchronizer engages with the clutching teeth of first gear and locks the gear to the main shaft, allowing power to flow from the input gear through the countershaft and to first gear and the main shaft. Who is correct?
a. Technician A only
b. Technician B only
c. Both A and B
d. Neither A nor B

When discussing the various gear positions of a transfer case, Technician A says that when the transfer case is in low, the overall gear ratio is numerically increased. Technician B says that when the transfer case is in the high position, the vehicle operates in an overdrive mode due to the decrease in torque multiplication. Who is correct?
