Quick Check

  1. Check level and condition of transaxle fluid. Check PCM memory for stored Diagnostic Trouble Codes (DTCs). See HYDRA-MATIC 4T60-E DIAGNOSIS article. If no DTCs are present, go to next step. If DTCs are present, diagnose and repair all PCM-related trouble codes. Clear PCM trouble code memory.
  2. Perform road test. See ROAD TEST  under TESTING. During road test, record shift points. If shift point timing or shifting is incorrect, see HYDRA-MATIC 4T60-E DIAGNOSIS article.
  3. If shift(s) is too harsh or too soft, see HYDRAULIC PRESSURE TESTS  under TESTING. For specific complaints, see appropriate condition(s) listed under SYMPTOM DIAGNOSIS  under TROUBLE SHOOTING.
