Road Test

NOTE: If shift lever cannot be moved from "P" with brake pedal depressed and accelerator at idle position, check shift interlock system. See RO ELECTRONIC CONTROLS article.
  1. Warm engine to normal operating temperature. Apply parking brake, and block wheels. Start engine, and move shift lever to "D" while depressing brake pedal. Depress accelerator pedal and release it suddenly. Engine should not stall.
  2. Repeat step  1 with shift lever in "S", and ensure engine does not stall. Road test vehicle, and check for abnormal noise and clutch slippage. See CLUTCH APPLICATION  table for clutch engagement specification.
  3. Ensure shift points are correct. See UPSHIFT SPECIFICATIONS (MPH)  and DOWNSHIFT SPECIFICATIONS (MPH)  tables.
  4. With shift lever in "D", accelerate to about 35 MPH so transaxle is in 4th gear. Move shift lever to "2" position, and ensure engine braking occurs.
    CAUTION: DO NOT  shift from "D" or "S" to "2" at speeds greater than 62.5 MPH, or transaxle may be damaged.
  5. Place shift lever in "2". Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage. Upshifts and downshifts should not occur in this range.
  6. Place shift lever in "R". Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage.
  7. Park vehicle on a slope. Apply parking brake, and place shift lever in "P". Release parking brake, and ensure vehicle does not move. If vehicle moves, check for defective shift cable or parking components.
