Initial Inspection and Diagnostic Overview

A: INSPECTION
1. 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.

2. Shift Patterns








Check "kick-down".

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

3. Engine Brake Operation

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

4. 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.
