"D" Range Test

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 1994 Toyota MR2, 1993 Toyota MR2, 1993 Toyota Celica, 1992 Toyota MR2, and 1992 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
  1. Shift into "D" range. Hold accelerator pedal constantly at full throttle position. Check 1-2, 2-3 and 3-OD upshift points.
    • If no 1-2 gear upshift occurs, governor valve, 1-2 shift valve or No. 2 solenoid is faulty.
    • If no 2-3 gear upshift occurs, 2-3 shift valve or No. 1 solenoid is faulty.
    • If no 3-OD gear upshift occurs, 3-OD shift valve is faulty or solenoid valve or circuit is faulty.
    • If all shift points are incorrect, throttle cable adjustment, throttle valve, 1-2 shift valve, 2-3 shift valve or 3-OD shift valve is faulty.
    • If all lock-up points are incorrect, lock-up relay valve or lock-up solenoid is faulty.
  2. Use procedure outlined in step  1 to check for shock and slip between 1-2 gear, 2-3 gear and 3-OD gear upshifts. If shock is harsh, line pressure is too high on the accumulator or check ball is faulty.
    CAUTION: When checking for abnormal noise or vibration, use extreme care, as problem may be due to an out-of-balance drive shaft, differential, torque converter, tire, or faulty power train rubber mounts.
  3. Run vehicle in "D" range lock-up or overdrive gear. Check for abnormal noise and vibration. Ensure lock-up occurs at appropriate speeds. Refer to appropriate table under SHIFT SPEED SPECIFICATIONS .
  4. While running in "D" range, 2nd, 3rd and OD gears, confirm correct kickdown vehicle speed limits for 2nd-1st, 3rd-2nd and OD-3rd gears. Check for abnormal shock and slip at kickdown. Abnormal shock and slip at kickdown may be caused by throttle cable misadjustment, faulty throttle valve, or faulty shift valves.
  5. While running at 37 MPH in "D" range, OD gear, or lock-up, lightly depress accelerator pedal. Ensure engine RPM does not change abruptly. If a large increase in RPM occurs, lock-up mechanism is faulty.
NOTE: To prevent overrun, transaxle shifts into 3rd gear at 101 MPH. In "2" range, there will be no lock-up to 2nd gear.
