Torque CONVERTOR Engagement Test

NOTE: Retrieve and record DTCs. See QUICK TEST  . Repair all DTCs before performing the following test.
  1. Connect tachometer. Warm engine to normal operating temperature. Ensure transaxle fluid level is correct. Drive vehicle and maintain vehicle speed at about 50 MPH. Release throttle for about 2 seconds, then reapply to previous setting. Engine RPM should increase when throttle is released and decrease in about 5 seconds after throttle is reapplied. Go to next step.
  2. Maintain vehicle speed at about 50 MPH. Apply light pressure to brake pedal so that brakelights operate. Engine RPM should increase as brake pedal is tapped, and then decrease about 5 seconds after pedal is released. If torque converter clutch operation is not as specified, perform TEST C  under SYSTEM TESTS. If concern is still present, see TCC operation concerns listed in SYMPTOM DIAGNOSIS under TROUBLE SHOOTING.
