Installation
1.
Install in the reverse order of removal.
   
In case of the reinstallation
1)
Replace the oil seal with a new one by using special tool (09453-3L240, 09231-H1100) when ATF leak occurs due to differential oil seal damage.
2)
Check the ATF level after refilling the automatic transaxle with fluid.
(Refer to Hydraulic System - "Fluid")
3)
Clear the diagnostic trouble codes (DTC) using the GDS.
(The DTCs will not be cleared even after the battery negative terminal has been disconnected. So, be sure to clear the DTCs using the GDS.)
In case of replacing with a new automatic transaxle
1)
New automatic transaxle is already filled with specified quantity of ATF.
For that reason, it is not necessary to refill and check the ATF, however, the remaining ATF in the ATF cooler has to be removed.
2)
Install the transaxle after removing the remaining ATF by blowing air into ATF cooler hose.
3)
Clear the diagnostic trouble codes (DTC) using the GDS.
(The DTCs will not be cleared even after the battery negative terminal has been disconnected. So, be sure to clear the DTCs using the GDS.)
4)
Reset the automatic transaxle adaptive values using the GDS.

5)
Perform the TCM adaptive values learning procedure.
(Refer to Automatic Transaxle Control System - "Repair procedures")
In case of replacing with a remanufactured automatic transaxle
1)
Remanufactured automatic transaxle is not filled with specified quantity of ATF.
For that reason, it is necessary to refill and check the ATF.
2)
Check the ATF level after refilling the automatic transaxle with fluid.
(Refer to Hydraulic System - "Fluid")
3)
Clear the diagnostic trouble codes (DTC) using the GDS.
(The DTCs will not be cleared even after the battery negative terminal has been disconnected. So, be sure to clear the DTCs using the GDS.)
