1. Transmission safety information
Caution
- Be careful not to cause any damage.
- Because damage to the rib especially decreases the case strength, even greater caution is necessary when handling the rib sections.
Warning
- When performing work on heavy items such as the case and gears, take care to prevent injury.
2. Preliminary and post procedures
1. Preliminary procedures
1) Open the engine hood.
2) Disconnect the battery cable from the battery negative terminal.
Caution
- After turning OFF the ignition switch (power mode for models with passive entry and start system), do not disconnect the battery cable within 3 minutes.
- If the battery cable is disconnected within 3 minutes, the vehicle electronic control system may malfunction.
- If the battery cable is disconnected, perform the setting of the front door power window switch with AUTO UP/AUTO DOWN function after connecting the battery negative terminal.
3. Transfer preparation
1. 4WD models
1) Change the transfer mode to 2WD using the 2-4 switch.
Caution
- Before removing the transfer from the vehicle, change the transfer mode to 2WD using the 2-4 switch.
4. Engine hood removal
5. Engine cover removal
1) Remove the engine cover from the engine.
6. Wiper linkage disconnect
7. Cowl panel removal
1) Remove the cowl panel from vehicle.
8. Transmission preparation
1) Raise the vehicle using a jack.
Note
- Use a suitable stand to support the vehicle.
Caution
- The accurate ATF amount cannot be measured if the vehicle is at an angle. Perform work within ±1° inclination of the vehicle front and rear.
9. Transmission air deflector removal
1) Remove the transmission air deflector from the frame.

10. Coolant drain
Refer to the following items about engine coolant draining.
Refer to "1.Engine 1D.Cooling(4JJ3 with DPD) coolant replacement".
Refer to "1.Engine 1D.Cooling(4JJ3 without DPD) coolant replacement".
Refer to "1.Engine 1D.Cooling(RZ4E-TC) coolant replacement".
11. ATF drain
When the transmission is disassembled.
1) Remove the drain plug from the oil pan.
2) Drain the ATF.
Note
- Keep a record of the amount of fluid that is drained.
Caution
- If chips and particles are found on the oil cleaner magnet when examining it, damage on the gear is suspected.
- Examine the chips and particles on the oil cleaner magnet to determine what type of wear has occurred in the transmission.
3) Temporarily tighten the drain plug to the oil pan.
12. Rear propeller shaft removal
13. Front propeller shaft removal
1. 4WD models
Refer to "3.Driveline, Axle 3C.Drive Shaft System front propeller shaft removal".
14. ATF cooler/warmer removal
