Exam 43: Automatic Transmission and Transaxle Service

Technician A says a prerequisite to accurate road testing analysis includes knowing what bands and clutches are applied in a particular gear range. Technician B says slipping conditions can be caused by a leaking hydraulic circuit. Who is correct?

If a transmission problem cannot be identified from an inspection or road test, a ____________________ test should be performed.

A technician is diagnosing a vehicle that does not crank over when the gear selector is in park or neutral but does crank when the gear selector is in Reverse and Drive. Technician A says the neutral safety switch could need adjustment. Technician B says the gear selector linkage could need adjustment. Who is correct?

Technician B says the shifter linkage needs adjustment. Who is correct?

Two technicians are trying to install a remanufactured transmission and torque converter in a vehicle. No matter how well they align the transmission with the engine, the transmission will not slide onto the dowel pins. Technician A says the pilot hub on the converter could be damaged.

Technician A checks for worn or broken transmission mounts by prying on the transmission case with a pry bar while watching the mount. Technician B checks for worn or broken transmission mounts by running the engine at 1,500 rpm, with the transmission in drive and then in reverse , while he watches the torque reaction (movement)of the engine. Who is correct?

Technician A says the only positive way to identify the exact design of the transmission is by the shape of its oil pan. Technician B says identification numbers only identify the manufacturer and assembly date of the transmission. Who is correct?
