Is any malfunction detected by self-diagnostic results?
YES >> Check the malfunctioning system. Refer to AT- 8 6 , "SELF-DIAGNOSTIC RESULT MODE" , AT- 9 3 ,
"Judgment Self-diagnosis Code" .
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 LINE PRESSURE
Check line pressure at the engine stall point. Refer to AT- 5 0 , "
LINE PRESSURE TEST" .
OK or NG
OK >> GO TO 6.
NG - 1 >> Line pressure high. GO TO 4.
NG - 2 >> Line pressure low. GO TO 5.

Control Valve with TCM and A/T Fluid Temperature Sen-
sor 2" .
2. Disassemble A/T. Refer to AT- 2 5 5 , "
DISASSEMBLY" .
3. Check the following.
–Oil pump assembly. Refer to AT- 2 7 1 , "Oil Pump" .

4. Disconnect heated oxygen sensor 2 harness connectors (A).
: Vehicle front
: Bolt
5. Remove heated oxygen sensor 2 harness (B) from clips (1).
6. Remove bracket (2) from transmission assembly.
7. Disconnect A/T assembly harness connector.
8. Remove snap ring from A/T assembly harness connector.
9. Push A/T assembly harness connector.
CAUTION:
Be careful not to damage connector.
10. Remove clips (1), oil pan (2) and oil pan gasket.
: Vehicle front
: Oil pan mounting bolt
Drain bolt (3)
11. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF 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".
