(2)
Reset the automatic transaxle adaptive values using the GDS.

(3)
Perform the oil pressure characteristics input procedure.
(1)
If you can access the internet, perform the oil pressure characteristics input procedure using the GDS.

(2)
If you can not access the internet, record the bar code data (oil pressure characteristics) on the automatic transmission case and then input it manually onto the GDS.

(4)
Perform the TCM adaptive values learning procedure.
(Refer to Automatic Transaxle Control System - "Repair procedures")
4.
In case of the replacing with a remanufactured automatic transaxle.
