Installation

To install, reverse the removal procedure.

Follow the separted each procedure as below according to reinstallation or replacing with a new automatic transaxle.

In case of the reinstallation.

(1)

Replace the oil seal with a new one when ATF leak occurred because of differential oil seal damage.

When installing the new oil seal, use the special service tool(SST No.:09452-26100, 09231-H1100).

(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.

Even though disconnecting the battery negative terminal, the DTCs will not be cleared. So, be sure to clear the DTCs using the GDS.

In case of the replacing with a new automatic transaxle.

New automatic transaxle is already filled with specified quantity ATF.

For that reason, it does not necessary to refill and check the ATF but the remaining ATF inside of ATF cooler have to be removed.

(1)	Set the air blow gun in front of the ATF cooler hose (A).

(2)	Set the cup in front of the ATF cooler hose (B).

(3)	Remove the remaining ATF by blowing air into ATF cooler hose (A).

(4)	Install the ATF cooler hose (A) and (B).

(5)

Clear the diagnostic trouble codes (DTC) using the GDS.

Even though disconnecting the battery negative terminal, the DTCs will not be cleared. So, be sure to clear the DTCs using the GDS.

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

(7)	Perform the oil pressure characteristics input procedure. • Oil pressure characteristics(bar code) location • Oil-pressure characteristics input(Transmision exchange)

(8)	Perform the TCM adaptive values learning procedure. (Refer to Automatic Transaxle Control System - "Repair procedures")
