Exam 19: Transmission Reinstallation

If the battery was disconnected, the adaptive memory may need to be reset.

Technician A says you can clean a transmission cooler and lines using the shop's parts cleaning tank. Technician B says you can clean a transmission cooler and lines with an aerosol flushing kit. Who is correct?

Which of the following should be inspected before reinstalling the transmission?

If required, make sure to look up any procedures for resetting the adaptive memory after an automatic transmission rebuild so the Powertrain Control Module will reprogram its shift timing and pressures for the newly rebuilt transmission.

Tech A states that you should use the transmission bolts to pull the transmission into the engine. Tech B states that the transmission should slide over the dowel pins and against the engine easily. Who is correct?

Technician A says some vehicles are equipped with a dust cover that needs to be removed to access the bolts connecting the torque converter to the flywheel. Technician B says when removing a transmission, you do not need to disconnect the transmission cooler lines. Who is correct?

Tech A states that flexplates can be installed in any direction. Tech B states that flexplate bolts need to be tightened with an impact gun to prevent the engine from spinning. Who is correct?

The flexplate holes are not evenly spaced. This helps in:

Technician A says that when inspecting the torque converter, you need to check the snout of the converter where the seal and bushing rides for excessive wear. Technician B says that the internal end play of the converter must be checked. Who is correct?

Tech A states that transmission electrical connectors should be filled with RTV to prevent water from getting into the contacts. Tech B states that the seals on electrical connectors should be checked for damage and replaced if they are damaged. Who is correct?

It is not necessary to get the torque converter fully seated when installing it into the transmission.

When installing a transmission in a front-wheel drive:

Technician A says that before test driving a recently rebuilt transmission, all DTCs should be erased. Technician B says that any cable adjustments should be verified before test driving. Who is correct?

When the automatic transmission is removed from the vehicle, which of the following needs to be checked on the flex plate?

Technician A says that the cooler and cooler lines should be flushed as part of a transmission rebuild. Technician B says that if the cooler is not flushed oil returning from the cooler can carry debris into the torque converter, and cause damage to it. Who is correct?

Technician A says when installing the torque converter, make sure all three components, oil pump drive, stator support, and turbine input shaft, engage with their mating parts. Technician B says after rebuilding the transmission and installing it into the vehicle, it is not necessary to take a test drive or recheck the fluid level. Who is correct?

If the transmission's torque converter bolts will be reused, the technician should check the threads carefully for damage and wear.

Tech A states that you should use the transmission bolts to pull the transmission into the engine. Tech B states that the transmission should slide over the dowel pins and against the engine easily. Who is correct?

Proper removal and installation of an automatic transmission are just as critical as following the proper rebuilding techniques and practices for that transmission.

What can a leaking automatic transmission fluid cooler cause?
