Operating Principles Of Each Range
1. N range
Since the forward and reverse brakes are released, driving force of input shaft is not transmitted to output shaft.
2. P range
A. Since the forward and reverse brakes are released, as those in the N range, driving force of input shaft is not transmitted to
output shaft.
B. Parking pawl that is linked with select lever parking gear meshes with and fastens output shaft mechanically.
3. D, M2, M3, M4, M5 range 1st speed
A. Fastens the front brake.
B. The front brake and the forward one-way clutch regulate reverse rotation of the mid sun gear.
C. The 1st one-way clutch regulates reverse rotation of the rear sun gear.
D. The 3rd one-way clutch regulates reverse rotation of the front sun gear.

g
1. Park the vehicle on a flat road and lock the tires.
2. Shift the shift lever to the "P" range.
3. Remove the overflow plug by using a torx wrench.
4. Remove the filler plug by using a torx wrench.
5. Check if ATF flows out of the overflow hole. If ATF does not drop, add ATF until it drops.
6. Fix the overflow plug by using Torx wrench.
Reuse the used gasket.
7. Add 1400cc of ATF from the oil filling hole.
8. Install it to the filler plug with a new gasket.
9. Tighten the filler plug by using Torx wrench with the specified torque.
Tightening torque :
15~25 Nm (1.5~2.5 kgf.m, 11.1~18.4 lb-ft)
10. Start the engine.
11. Raise ATF temperatirue on CAN signal up to 50°C at stabilized idle speed condition.
12. Shift from "P" to "D", then from "D" to "P", keeping each shift position "N","R" more than 2 seconds with foot
braking.
13. Repeat 2 times above procedure "3".
14. Remove the overflow plug and the O-ring by using Torx wrench.

15. Check If the thin oil stream becomes drop by drop when ATF temperatirue on CAN signal is at 58~64°C.
16. Install it to the overflow plug with a new gasket.
17. Tighten the overflow plug by using Torx wrench with the specified torque.
Tightening torque :
35~45 Nm (3.6~4.6 kgf.m, 25.8~33.2 lb-ft)
Be sure to wipe off spilled ATF completely after tightening the overflow plug.

Diagnostic Trouble Codes(Inspection Procedure)
1. Turn the ignition switch to OFF.
2. Connect the Hi-scan tool to the DLC connector for diagnosis.
3. Turn the ignition switch to ON.
4. Check the diagnostic trouble codes using the Hi-scan tool.
5. Read the output diagnostic trouble codes. Then follow the remedy procedures according to the "DIAGNOSTIC
TROUBLE CODE DESCRIPTION" on the following pages.
• A maximum of 10 diagnostic trouble codes (in the sequence of occurrence) can be stored in the Random
Access Memory (RAM) incorporated within the control module.
• The same diagnostic trouble code can be stored one time only.
• If the number of stored diagnostic trouble codes or diagnostic trouble patterns exceeds 10, already stored
diagnostic trouble codes will be erased in sequence, beginning with the oldest.
• If the same trouble code does not occur during 40 times continuously, memorized trouble code would be
deleted automatically when the ATF temperature reaches 50°C(122°F).
6. Delete the diagnostic trouble code.
7. Disconnect the Hi-scan tool.
DTC cleaning should only be done with the scan tool.
