Read data list
Hint:
Using the intelligent tester's data list allows switch,
sensor, actuator and other item values to be read without
removing any parts. Reading the data list early in
troubleshooting is one way to save time.

Inspection
Inspect automatic transaxle oil panel
sub-assembly
Remove the magnets and use them to collect any
steel chips. Examine the chips and particles in the
pan and on the magnet to determine what type of
wear has occurred in the transaxle.
Steel (magnetic): bearing gear and plate ...
