SELF-DIAGNOSTIC RESULT MODE" .
Do the self-diagnostic results indicate PNP switch, ATF pressure switch 5?
YES >> Check the malfunctioning system. Refer to AT- 11 2 , "DTC P0705 PARK/NEUTRAL POSITION
SWITCH" , AT- 1 8 2 , "DTC P1845 ATF PRESSURE SWITCH 5" .
NO >> GO TO 2.
2. CHECK A/T FLUID LEVEL
Check A/T fluid level. Refer to AT- 1 2 , "
Checking A/T Fluid" .
OK or NG
OK >> GO TO 3.
NG >> Refill ATF.
3. CHECK CONTROL LINKAGE
Check the control linkage.

Refer to AT- 2 3 4 , "Checking of A/T Position" .
OK or NG
OK >> GO TO 4.
NG >> Adjust control linkage. Refer to AT- 2 3 4 , "
Adjustment of A/T Position" .
4. MANUAL MODE SWITCH
Check the manual mode switch. Refer to AT- 1 7 2 , "
DTC P1815 MANUAL MODE SWITCH" .
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.
5. CHECK A/T FLUID CONDITION
1. Remove oil pan. Refer to AT- 2 4 2 , "
Control Valve with TCM and A/T Fluid Temperature Sensor 2" .

6. Remove snap ring from A/T assembly harness connector.
7. Push A/T assembly harness connector.
CAUTION:
Be careful not to damage connector.
8. Remove oil pan and oil pan gasket.
9. Check foreign materials in oil pan to help determine causes of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.

If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT- 1 4 , "
A/T Fluid Cooler Cleaning" .
10. Remove magnets from oil pan.
