AUTOMATIC TRANSAXLE ATF COOLER FLUSHING
This TSB supersedes TSB 12-AT-019 to include additional vehicles.
DESCRIPTION:
Whenever an automatic transaxle is replaced, the ATF cooler must be flushed to remove
contaminants such as metal particles and clutch material. Failure to flush or improper flushing of the
ATF cooler may result in severe damage to the replacement transaxle.
This TSB applies to transmissions with the ATF cooler in the radiator or the ATF warmer/cooler
attached to the transmission. This TSB does not apply to dual-clutch transmissions.
YF HEV and LF HEV remanufactured transmissions have a new ATF warmer/cooler installed and do
not need to be flushed.
