6.	Using the elephant jack, support the engine.

7.	Remove the starter cover (A).

8.	Remove the engine support bracket (B). Tightening torque Start cover: 8.8 ~ 13.7 N.m (0.9 ~ 1.4 kgf.m ~ 10.1 lb-ft) Engine support bracket bolt: 49.0 ~ 63.7 N.m (5.0 ~ 6.5 kgf.m, 36.2 ~ 47.0 lb-ft) Engine mounting nut: 63.7 ~ 83.4 N.m (6.5 ~ 8.5 kgf.m, 47.0 ~ 61.5 lb-ft)

9.	Disconnect starter connector (A) and cable (B) from the start "B" terminal.

10.	Remove the starter (A). Tightening torque : 49.0 ~ 63.7 N.m (5.0 ~ 6.5 kgf.m, 36.2 ~ 47.0 lb-ft)

11.	Disconnect the oil cooler tube (A). • Replace the O-ring(A) before reinstalling the oil cooler tube. • After the installation, start the engine and then check if there are any leakages from the hose.

12.	Disconnect the cooler hose (A).

13.	After removeing the mounting bolts, remove the ATF warmer (B). • Carefully install the clamp not to damage the hose. • Install the clamp in a correct direction not to interfere with other parts. • After the installation, start the engine and then check if there are any leakages from the hose.

14.	Remove the CKPS (A). Tightening torque : 6.9 ~ 9.8 N.m (0.7 ~ 1.0 kgf.m, 5.1 ~ 7.2 lb-ft)

15.	Remove the torque converter mounting bolts (A-6ea) by rotating the crank shaft pulley. Tightening torque : 45.1 ~ 52.0 N.m (4.6 ~ 5.3 kgf.m, 33.3 ~ 38.3 lb-ft)

16.	Disconnect the AWD ECU connector (A).

17.	Disconnect the wiring (B) from the transfer case(AWD) and transmission.

18.

Remove the transfer case(AWD) (A) from the transmission. Tightening torque : 29.4 ~ 41.2 N.m (3.0 ~ 4.2 kgf.m, 21.7 ~ 30.4 lb-ft) Precautions of the transfer case handling A. Preventing damage to the ITA (Integrated Transfer case Actuator) 1) In case of transporting the transfer case • Use caution for the ITA not to collide to the other parts when it is lifted from the transporting package. • Use caution for the ITA not to be impacted by the floor or structure. 2) In case of assembling the transmission • Use caution for the ITA not to be impacted by the transmission, floor or structure. B. Preventing oil leakage • Use caution when disassembling/installing the transfer case. If the horizontal position is disturbed, oil may be leaked even with the air breather valve installed because oil remains inside the transfer case.

19.	Remove the E-module connector (A).

20.	Disconnect the wiring (B) from the transmission.

21.	Disconnect the starter "B"terminal wiring (A) after removing mounting bolts.

22.	Disconnect the inhibitor switch connector (A).

23.	Disconnect the wiring (B) from the transmission.

24.	Using the transmission jack, support the transmission.

25.	After loosening the mounting bolts, remove the transmission from the engine. Tightening torque : [A] 63.7 ~ 83.4 N.m (6.5 ~ 8.5 kgf.m, 47.0 ~ 61.5 lb-ft) [B] 39.2 ~ 46.1 N.m (4.0 ~ 4.7 kgf.m, 28.9 ~ 34.0 lb-ft) [C] 34.3 ~ 46.1 N.m (3.5 ~ 4.7 kgf.m, 25.3 ~ 34.0 lb-ft)

Installation

1.	To install, reverse the removal procedure. Follow the separted each procedure as below according to reinstallation or replacing with a new automatic transaxle.

2.

In case of the reinstallation. (1) Check the ATF level after refilling the automatic transaxle with fluid. (Refer to Hydraulic System - "Fluid") (2) Clear the diagnostic trouble codes (DTC) using the GDS. The DTCs are not cleared even by disconnecting the battery negative terminal. So, be sure to clear the DTCs using the GDS.

3.

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) 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. (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. Remanufactured automatic transaxle is not filled with specified quantity ATF. For that reason, it is necessary to refill and check the ATF. (1) Check the ATF level after refilling the automatic transaxle with fluid. (Refer to Hydraulic System - "Fluid") (2) 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. (3) Reset the automatic transaxle adaptive values using the GDS. (4) 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. (5) Perform the TCM adaptive values learning procedure. (Refer to Automatic Transaxle Control System - "Repair procedures")
