Important: The bleeding process is repeated until the
oil remains at the Full Cold line in the reservoir after
purging. Failure to properly perform this procedure
can result in irreparable damage to the transaxle drive
system.
Note: The filter and oil are changed at the same time. Do
not reuse oil. Once the new filter is installed and oil is added
any air in the system must be purged.
