Test 1 Selector In Low 1ST Gear

1. Attach gauges to line and low-reverse ports.
2. Operate engine at 1000 rpm for test.
3. Move selector lever on transaxle all the way rearward (1 position).
4. Read pressures on both gauges as throttle lever on transaxle is moved from full clockwise position to full counterclockwise position.
5. Line pressure should read 52 to 58 psi with throttle lever clockwise. Pressure should gradually increase to 80 to 88 psi as lever is moved counterclockwise.
6. Low/reverse pressure should read the same as line pressure, within 3 psi.
7. This tests pump output, pressure regulation, and condition of rear clutch and rear servo hydraulic circuits.
