  1. This tests oil pump output and pressure regulation. Remove pressure tap plug and install pressure gauge in accumulator pressure tap. See Figure . Start and operate engine at 1000 RPM.
  2. Move manual selector lever on transmission to fully forward position and then rearward one position to gearshift "2" position. Read pressure on pressure gauge as throttle valve lever on transmission is moved from fully forward position to fully rearward position.
  3. Line pressure at accumulator pressure tap should be 54-60 psi (3.7-4.2 kg/cm2 ) with throttle valve lever fully forward and gradually increase to 90-96 psi (6.3-6.7 kg/cm2 ) as throttle valve lever is moved rearward.
  4. If line pressure is not within specification, adjust line pressure. See LINE PRESSURE  under HYDRAULIC PRESSURE ADJUSTMENTS. If proper line pressure still cannot be obtained, check for defective components and hydraulic circuit. Remove pressure gauge. Install and tighten pressure tap plug to specification. See TORQUE SPECIFICATIONS  .
