Exam 43: Automatic Transmission and Transaxle Service

What transmission problems can be caused by broken or loose driveline mounts?

When should the ATF level be checked on most vehicles?

Name four causes of low transmission fluid pressure.

Technician A says that if the ATF has a dark brownish or blackish color and a burnt odor, the fluid has been overheated. Technician B says that if the fluid has a milky color, this indicates that engine coolant has been leaking into the transmission cooler. Who is correct?

A technician is diagnosing a transmission fluid leak problem. With the inspection cover removed, there is fluid on the back of the converter shell, but the front of the converter is dry. What is the most likely source of the leak?

When performing a stall test, the throttle should be held wide open for ten seconds.

How is the fluid level checked on a transmission that doesn't have a dipstick?

Technician A says any engine movement may change the effective length of the shift and throttle cables. Technician B says if the driveline mounts are in good condition, there should be no engine movement when the throttle pedal is depressed with the brakes fully applied. Who is correct?

____________________ pressure is used as an indicator of engine load and influences the speed at which automatic shifts will occur.

During rebuilding, what three transmission components should be checked for warpage?

List the steps to take in diagnosing an automatic transmission problem.

Which of these engine control sensors is unlikely to cause shifting problems?

Technician A says the only positive way to identify the model of a transmission is by the shape of the oil pan. Technician B says the only positive way to identify the transmission model is by the ID number stamp or sticker on the transmission case. Who is correct?

All late model automatic transmissions are equipped with a(n)____________________ torque converter.

You should consult the manufacturer's service information to find the correct operating temperature and  conditions for an accurate transmission fluid check.

Always lubricate seals with ____________________ prior to installation.

Typically, transmission __________ should not drop more than 15 psi (1 kg/cm ² )between shifts.

A plugged transmission cooler line or a restricted cooler can cause the vehicle to stall when shifted into reverse.

Red fluid leaking from the bellhousing is an indication of a defective ____________________.

Some manufacturers require replacement of the transmission cooler whenever the transmission is overhauled.
