Common Symptoms

  • Check Engine Light illuminated
  • Harsh or erratic shifting
  • Speedometer malfunction
  • Transmission slipping

Probable Causes (Ranked by Likelihood)

  • Faulty input speed sensor Very High
  • Damaged reluctor ring inside transmission High
  • Contaminated transmission fluid with metal debris Moderate
  • TCM input circuit fault Low

Step-by-Step Diagnostic Procedure

  1. Monitor input speed sensor reading on a scan tool -- it should increase smoothly with engine RPM in gear

  2. Compare input speed to output speed -- the ratio should match the current gear ratio

  3. Check transmission fluid for metal particles or dark coloration

  4. Inspect input speed sensor connector for damage

  5. Replace the input speed sensor if readings are erratic

Input/turbine speed sensor circuit range fault is typically the input speed sensor on the transmission or low/contaminated fluid. Check fluid level and condition first. The sensor is usually externally mounted and accessible. Metal debris on the sensor tip points to internal trans wear, so inspect what you remove.
