5. Accelerate vehicle to 20 to 25 km/h (12 to 16 MPH) under the following conditions and release the accel-
erator pedal completely.
THROTTLE POSI: Less th an 1.0/8 (at all times during step 4)
SLCT LVR POSI: “D” position
- Make sure that “GEAR” shows “2” after releasing pedal.
6. Depress accelerator pedal to WOT (more than 7.0/ 8 of “THROTTLE POSI”) quickly from a speed of 20 to
25 km/h (12 to 16 MPH) until “TESTING” changes to “STOP VEHICLE” or “COMPLETED”. (It will take
approximately 3 seconds.)
If the check result NG appears on CONSULT-III screen, go to AT-111, " Diagnosis Procedure " .
If “STOP VEHICLE” appears on CONSULT-III screen, go to the following step.
- Make sure that “GEAR” shows “1” when depressing accelerator pedal to WOT.
- If “TESTING” does not appear on CONSULT-III fo r a long time, select “SELF-DIAG RESULTS” for
“TRANSMISSION”. In case a DTC other than “P0731 A/T 1ST GR FNCTN” is shown, refer to AT-79," CONSULT-III Function (TRANSMISSION) " .
7. Stop vehicle.
8. Follow the instruction displayed. (Check for normal shifting referring to the table below.)
9. Make sure that “OK” is disp layed. (If “NG” is displayed, refer to “Diagnostic Procedure”.)
Refer to AT-111, " Diagnosis Procedure " .
Refer to AT-64, " Vehicle Speed at Which Gear Shifting Occurs " .
WITH GST
Follow the procedure “WITH CONSULT-III”.

2. Check to ensure that:
- Valve, sleeve and plug slide along valve bore under their own weight.
- Valve, sleeve and plug are free from burrs, dents and scratches.
- Control valve springs are free from damage, deformation and fatigue.
- Hydraulic line is free from obstacles.

NG >> Check control valve again. If NG, repair or replace control valve assembly.

Diagnosis Procedure " .
If “STOP VEHICLE” appears on CONSUL T-III screen, go to following step.
- Make sure that “GEAR” shows “2” wh en depressing accelerator pedal to WOT.
- If “TESTING” does not appear on CONSULT-III fo r a long time, select “SELF-DIAG RESULTS” for
“TRANSMISSION”. In case a DTC other than “P0732 A/T 2ND GR FNCTN” is shown, refer to AT-79," CONSULT-III Function (TRANSMISSION) " .
