Road Test "D" Range: Testing

Perform TESTING PREPARATION PROCEDURES. Connect vacuum gauge, EC-AT tester, tachometer and pressure gauges to vehicle.

NOTE: For complete EC-AT tester information, see text under SELF-DIAGNOSIS  .
  1. Shift to "D" while in ECONOMY mode on 929 (NORMAL mode on RX7) and accelerate vehicle at half and full throttle valve opening. Throttle sensor voltage on EC-AT tester (if used) represents throttle valve opening. Vacuum on other testers represents throttle opening.
  2. Ensure 1-2, 2-3 and 3-OD upshifts, downshifts and lock-up are obtained. Shift speed can be checked with EC-AT tester checking turbine RPM or a tachometer.
  3. Use same procedure to check upshift for shift shock. Drive in OD, shift to "S" to check OD-3 downshift and release throttle to check for engine braking in 3rd and 2nd.
  4. Select "D" while in HOLD mode. Accelerate vehicle, check 2-3 upshift and downshift and for no 1st and OD. Check shift points, see appropriate SHIFT SPEED CHARTS  .
