Test H: Shock Or Lag Time When Shifting From Neutral To Drive & From Neutral To Reverse

WARNING: This page is about a different variant/trim than selected.
NOTE: If shock or lag time of 2 seconds or more occurs when transaxle is shifted from Neutral to Drive and from Neutral to Reverse with engine idling, likely cause may be abnormal line pressure, faulty oil pump, valve body or PCM.
  1. Measure hydraulic pressure for each element with gearshift lever in "D" and "R" positions. See HYDRAULIC PRESSURE TESTS  under PERFORMANCE TESTS. If pressure is within specification, go to next step. If pressure is not within specification, go to step  2 .
  2. Adjust line pressure. See HYDRAULIC PRESSURE ADJUSTMENTS  under PERFORMANCE TESTS. If symptoms are still present, go to next step.
  3. If shock occurs when shifting, go to next step. If shock occurs while starting off, go to step  5 .
  4. Remove transaxle assembly. See appropriate REMOVAL & INSTALLATION article in AUTOMATIC TRANSMISSIONS. Replace oil pump assembly. See appropriate OVERHAUL article. If symptom is eliminated, diagnosis is complete. If symptom is not eliminated, replace PCM. See appropriate REMOVAL, OVERHAUL & INSTALLATION article in ENGINE PERFORMANCE.
  5. Disassemble valve body and inspect. See appropriate OVERHAUL article. Check for loose bolts, damaged "O" rings, valves and valve bodies. Repair or replace as necessary. If symptom is eliminated, diagnosis is complete. If symptom is not eliminated, replace PCM. See appropriate REMOVAL, OVERHAUL & INSTALLATION article in ENGINE PERFORMANCE.
