Initial Inspection and Diagnostic Overview

GENERAL PRECAUTION
Road tests should be conducted to properly diagnose the condition of the automatic transmission.

CAUTION: When performing test, do not exceed posted speed limit.

SHIFT PATTERNS
Check "kick-down".








- D range:
1st <- 2nd <- 3rd <- 4th
1st -> 2nd -> 3rd -> 4th
- 3 range:
1st <- 2nd <- 3rd <- 4th
1st -> 2nd -> 3rd
- 2 range:
2nd <- 3rd <- 4th
- 1 range:
1st <- 2nd <- 3rd <- 4th

ENGINE BRAKE OPERATION
Engine brake operation:
- D range -> 4th gear
- 3 range -> 3rd gear
- 2 range -> 2nd gear
- 1 range -> 1st gear

AWD FUNCTION
If "tight-corner braking" occurs when the steering wheel is fully turned at low speed:

1. Determine the applicable trouble code and check the corresponding duty solenoid C (transfer) for improper operation.
2. If the solenoid is operating properly, check transfer clutch pressure.
3. If oil pressure is normal but "tight-corner braking" occurs:
Check the transfer control valve for sticking, and the transfer clutch facing for wear.
