F4E-III & Fa4A-El

  1. Block wheels. Connect tachometer to engine. Connect appropriate pressure gauge to line pressure port (square head plug, marked "L"). See Fig 1.
  2. Run engine until normal operating temperature is obtained. Ensure engine is idling within specification. Refer to underhood emissions label. Shift transaxle into gear as applicable and record line pressure. Firmly apply brake pedal. Steadily increase engine RPM to WOT and record line pressure. Release accelerator. DO NOT allow engine to operate at full stall speed for more than 5 seconds.
  3. Before shifting into each gearshift lever position, run engine with transaxle in Neutral for one minute to cool transaxle. Repeat step  2 for each gear range. If line pressure is within specification, see STALL SPEED TEST . See LINE PRESSURE SPECIFICATIONS  table. If line pressure is not within specification, see HYDRAULIC PRESSURE TEST RESULTS .
