AUTOMATIC TRANSAXLE AND TRANSFER REMOVAL/INSTALLATIONA6E5714190902011. Disconnect the negative battery cable.
2. Remove the battery and battery tray.
3. Remove the aircleaner component. (See Sectin F.)
4. Remove the front tires and splash shield.
5. Remove the under cover.
6. Separate the steering shaft and steering hose. (See N–13 STEERING GEAR AND LINKAGE (4WD)
REMOVAL/INSTALLATION.)
7. Remove the front auto leveling sensor. (See Section T.)
8. Drain the ATF. (See K2–80 AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT.)
Warning
•Improperly jacking a transaxle is dangerous. It can slip off the jack and may cause serious injury.
Caution
•To prevent the torque converter and transaxle from separating, remove the transaxle without
tilting it toward the torque converter.
9. Remove in the order shown in the figure.
10. Install in the reverse order of removal.
11. Adjust the headlight zeroset. (See Section T.)
12. Add ATF to the specified level. (See K2–80 AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT.)
13. Carry out the mechanical system test. (See K2–72 MECHANICAL SYSTEM TEST.)
×: Test to be performed after the service work
14. Carry out the road test. (See K2–75 ROAD TEST.)
