After separating the transmission from the engine, remove the transmission by lowering the jack slowly.

Be careful not to damage other nearby systems or parts when removing the transmission assembly.

Installation

Install in the reverse order of removal

•	Matters that require attention when installing the transmission to engine

1)	Check that there is no gap between the torque converter housing (A) and the engine block (B).

2)	This gap means the torque converter is not assembled correctly and it can cause damage on the key (A) of oil pump gear. In this case, reinstall the torque converter correctly after removing the transamission assembly.

3)	If the bolt is tightened while there is a gap, it can cause damage on the key of oil pump gear. In this case, replace the transmission assembly after loosening the mounting bolts.

•	When reinstalling the automatic transmission assembly, perform the procedures below.

1)	Refill the engine coolant system radiator with coolant. [ATF warmer only] (Refer to Engine Mechanical System - "Coolant")

2)	Check the ATF level after refilling the automatic transmission with fluid. (Refer to Hydraulic System - "Fluid")

3)	Clear the diagnostic trouble codes (DTC) using the KDS. Disconnecting the battery negative terminal will not clear the DTCs. Clear DTCs using the KDS at all times.

•	When replacing with a new automatic transmission assembly, perform the procedures below.

1)	Refill the engine coolant system radiator with coolant. [ATF warmer only] (Refer to Engine Mechanical System - "Coolant")

2)	Automatic transmission is already filled with the specified amount of ATF. For this reason, it is not necessary to refill and check the ATF. However, the remaining ATF in the ATF cooler has to be drained.

3)	Clear the diagnostic trouble codes (DTC) using the KDS. Disconnecting the battery negative terminal will not clear the DTCs. Clear DTCs using the KDS at all times.

4)	Reset the automatic transmission adaptive values using the KDS.

5)	Perform the oil pressure characteristics input procedure using the KDS.

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