Chapter 39, Problem 8ASRQ
During a test drive, a noise that appears to be transmission related disappears when the driver brings the vehicle to a stop and disengages the clutch with the engine at idle. Technician A says that the noise may be caused by an internal transmission problem. Technician B says that the problem may be something interfering with the flywheel or pressure plate. Who is correct?
a. Technician A only
b. Technician B only
c. Both A and B
d. Neither A nor B
