Flushing
NOTICE:
If the transmission plastic baffle melted due to an overheat
condition, install a new cooler. The plastic cannot be cleaned out of a
cooler even with the heated cooler flusher.
NOTE:
The cooler bypass valve cannot be backflushed. When
backflushing the transmission fluid cooler the cooler bypass valve must
be removed from the transmission cooling system prior to backflushing
and cleaning.
-
NOTE:
Use transmission fluid specified for this
transmission. Do not use any supplemental transmission fluid additives
or cleaning agents. The use of these products could cause internal
transmission components to fail, which will affect the operation of the
transmission.
The transmission cooling system (cooler and lines) MUST
be flushed every time the transmission is overhauled or replaced in
order to minimize the likelihood of repeat repairs. It is mandatory that
proper equipment and procedures be followed when flushing
coolers/lines. The flushing equipment used MUST:
-
maintain fluid at 60°C (140°F) or above
-
pulsate fluid during cleaning
-
have twin magnetic filters
-
and have air purge capability before and after flushing.
-
If equipment meeting the specifications above is not
available, the transmission fluid cooler should be replaced and the
lines cleaned by hand.
-
Check and top off fluid level of the transmission cooling system heated flusher with transmission fluid.
