3- 2 [W3F1] AUTOMATIC TRANSMISSION AND DIFFERENTIAL
~
F : ROAD TEST
1 . GENERAL
Road tests should be conducted to properly diagnose
the condition of the automatic transmission .
When performing test, do not exceed posted speed
limit.
2. CHECKING FOR SHIFT PATTERNS
Check "kick-down" and engine brake operation .
D-range : 1st 2nd ±=; 3rd f=; 4th
3-range : 1st
2nd f=; 3rd -*=;: 4th (Manual switch OFF)
2nd ~=; 3rd t=; 4th (Manual switch ON)
2-range : 1st -,1-4 2nd 3rd ±=; 4th (Manual switch OFF)
2nd ±=; 3rd ±4 4th (Manual switch ON)
1-range: 1st t:; 2nd f= ; 3rd ±:; 4th
3. CHECK FOR THE 4WD 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.
(Refer to Disassembly and Inspection of the Transmis-
sion .)
