"D" Range Test

  1. Shift into "D" range. Hold accelerator pedal constant at full throttle. Check 1-2, 2-3, and 3-OD lock-up and upshift points. Refer to appropriate SHIFT SPEED SPECIFICATIONS .
    NOTE: There is no lock-up when vehicle speed is 6 MPH less than the set cruise control speed. Ensure cruise control is off during road test.
    • If no 1-2 upshift occurs, check 1-2 shift valve or governor valve.
    • If no 2-3 upshift occurs, check 2-3 shift valve.
    • If no 3-OD upshift occurs, check 3-OD shift valve or solenoid.
    • If all shift points are incorrect, check throttle valve, 1-2 shift valve, 2-3 shift valve and 3-OD shift valve.
    • If all lock-up points are incorrect, check lock-up relay valve or solenoid.
  2. Use procedure outlined in step 1) to check for shock and slip between 1-2, 2-3, and 3-OD upshifts. If shock is harsh, line pressure may be too high. Check accumulator or check ball.
  3. Run vehicle in "D" range lock-up or overdrive gear. 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 shaft, differential, tire, torque converter, etc.
  4. While running in "D" range, confirm correct kickdown vehicle speed limits for 2-1, 3-2, OD-3 shift points. Check for abnormal shock and slip at kickdown.
  5. Check lock-up function. Drive vehicle in OD gear of "D" range with lock-up on. Hold vehicle speed steady between 37-43 MPH. Lightly depress accelerator pedal. Ensure engine RPM does not change abruptly. Large increase in engine RPM indicates lock-up function is faulty.
