"D" Position

WARNING: This page is about a different car, the 2002 Toyota ECHO, 2002 Toyota Celica, 2001 Toyota ECHO, and 2001 Toyota Celica. However, it is still accessible from the selected car via links, so may be relevant.

Shift transaxle into Drive. Hold accelerator pedal constant at full throttle. Check 1-2, 2-3, and 3-4 upshift and lock-up points. See appropriate table in SHIFT SPEED SPECIFICATIONS and LOCK-UP SPEED SPECIFICATIONS .
NOTE:
There is no overdrive lock-up when coolant temperature is below 140°F (60°C) or when vehicle speed is 6 MPH less than the set cruise control speed. There is no lock-up when brake pedal is depressed.
- If no 1-2 upshift occurs, check lower valve body control valves or shift solenoid.
- If no 2-3 upshift occurs, check lower valve body control valves or shift solenoid.
- If no 3-4 upshift occurs, check 3-4 shift valve or shift solenoid.
- If all shift points are incorrect, check upper valve body, lower valve body control valves and 3-4 shift valve.
- If all lock-up points are incorrect, check lock-up relay valve or shift solenoid.
Use procedure outlined in step 1 to check for shock and slip between 1-2, 2-3 and 3-4 upshifts. If shock is harsh, line pressure may be too high. Check accumulator or check ball.
Drive vehicle in Drive during lock-up or Overdrive. Check for abnormal noise and vibration.
NOTE: Check for cause of abnormal noise and vibration must be made with extreme care as problem could be due to an unbalanced drive axle, differential, tire, torque converter, etc.
While driving in Drive, confirm correct kickdown vehicle speed limits for 2-1, 3-2, 4-3 shift points. Check for abnormal shock and slip at kickdown.
Check lock-up function. Drive vehicle in Overdrive ("D" position) with lock-up on. Hold vehicle speed steady at 37 MPH. Lightly depress accelerator pedal. Ensure engine RPM does not change abruptly. Large increase in engine RPM indicates lock-up function is faulty.
