TM 10-3930-659-34 4-30. CONVERTER-OUT PRESSURE TEST (Con’t). PRESSURE TEST 1. Install preformed packing (1) on adapter (2) and install adapter in transmission oil temperature sender port (5). 2. Install hose (4) and pressure gage (3) on adapter (2). 3. Start engine and run at fast engine idle speed for a maximum of 30 seconds (see TM 10-3930-659-10). 4. Reduce engine speed to slow engine idle speed and shift transmission direction selector lever to N (Neutral) (see TM 10-3930-659-10). NOTE Forklift truck must not move when performing step 5. 5. Move  transmission  speed  range  selector  lever  to  fourth  gear  and  transmission  direction  selector  lever  to  F (Forward) with engine at slow engine idle speed (see TM 10-3930-659-10). 6. Note pressure reading on pressure gage (3).  Pressure reading must be 70-100 psi (483-690 kPa).  If pressure reading is within specification, go to step 12. 4-132
