DESCRIPTION
Automatic Transaxle/Transmission (A/T) oil cooler and lines must be power flushed completely before an over-
hauled or replacement A/T is installed
ures is lack of lubrication to the front and rear planetary gears. This is usually caused by an accumulation of
metal particles and debris (from a previous A/T failure) on the internal mesh type baffle of the oil cooler. Power
flushing will remove the restriction by back flushing, followed by forward flushing to dislodge a restriction, then
back flushing again. This will in turn ensure full ATF flow for the transmission when it is operating.
NOTE: Repeat repairs caused by improper or lack of cooler line flushing will not be covered under warranty,
and are subject to review and debit by Mazda.
NOTE: For SKYACTIV-DRIVE, flushing is not recommended as part of service maintenance. There are no oil
cooler lines and the replacement SKYACTIV-DRIVE will come with a new oil cooler, which is mounted
directly to the case.
