Exam 43: Automatic Transmission and Transaxle Service

When using compressed air to clear a cooler line circuit of old fluid, debris, or solvent, avoid using air pressure higher than ____________________ psi.

Technician A says delayed shifts may be caused by leaking hydraulic circuits. Technician B says poor engine performance can cause delayed shifts. Who is correct?

Identify the three conditions that must be followed when performing a fluid level check.

Synthetic fluids tend to look and smell burnt after normal use; therefore, the appearance and smell of these fluids is not a good indicator of the fluid's condition.

Technician A says the transmission identification number is found on a sticker or stamped on the transmission case. Technician B says the vehicle certification label gives transmission information in a space marked TR. Who is correct?

Two technicians are discussing transmission fluid. Technician A says transmission fluid is red in color and has no dark or metallic particles suspended in it. Technician B says synthetic ATF is normally a darker red than petroleum-based fluid and tends to look and smell burnt after normal use. Who is correct?

A leaking transmission case can often be repaired with an epoxy-based sealant.

Two technicians are discussing band adjustment. Technician A says the band adjustment screws are located on the outside of the transmission case. Technician B says the band adjustment screws are located inside the transmission and the transmission pan must be removed to make the adjustments. Who is correct?

Identify at least three transmission components that may be the source of an ATF leak.

Installing the wrong transmission fluid can damage a transmission.

Slippage during shifting may indicate that a band needs adjustment.

A vibration that changes with a change in engine speed is most likely caused by a(n)______.

The transmission's fluid and filter should be changed only when there is an indication of oxidation or contamination.

What will be the symptoms of a throttle valve linkage that is adjusted too high?

In a nonelectronically controlled transmission, improper shift points are most commonly caused by a ______.

An engine vacuum leak can cause degraded shift quality.

A technician is diagnosing a car that lacks power during acceleration. There are no DTCs, and a check of the ignition and fuel system does not reveal any problems. Technician A says the exhaust system should be checked for a restriction. Technician B says the stator overrunning clutch inside the torque converter could be slipping. Who is correct?

Technician A says a stall test is performed to check the operation of the stator overrunning clutch inside the torque converter. Technician B says a stall test is performed to check the operation of the clutches and bands inside the transmission. Who is correct?

What tool is needed to properly adjust transmission bands?

Technician A says a low fluid level can cause fluid aeration. Technician B says a high fluid level can cause fluid aeration. Who is correct?
