Line Pressure Test

  1. Before testing line pressure, ensure throttle valve "B" pressure is within specification. See THROTTLE VALVE "B" PRESSURE TEST  .
  2. With engine off, remove plug from line pressure tap on transaxle. See Figure . Attach Pressure Gauge Set (07406-0020003) to line pressure tap using NEW aluminum washer. Tighten hose fitting to 13 ft. lbs. (18 N.m).
  3. Disconnect vacuum hose from top of vacuum modulator valve located on top of transaxle. See Figure . Connect vacuum pump to vacuum hose port on top of vacuum modulator valve.
  4. With shift lever in "P" or "N", start and operate engine at 2000 RPM. Note line pressure with no vacuum applied to vacuum modulator valve. Apply 20-23 in. Hg of vacuum to vacuum modulator valve, and note line pressure.
  5. Line pressure should be within specification. See HYDRAULIC PRESSURE TEST SPECIFICATIONS  table. If line pressure is not within specification, see HYDRAULIC PRESSURE TROUBLE SHOOTING  table. Shut engine off. Remove pressure gauge set. Install plug and vacuum hose.
NOTE: Check clutch pressure at each clutch pressure tap on transaxle. See Figure . Ensure shift lever is in proper position when checking clutch pressures.
