Test Three - Transmission In D Range Third Gear
NOTE: This test checks pressure regulation and condition of the clutch circuits. Both test gauges are required for this test.1. Turn OD switch off.
2. Leave vehicle on hoist and leave Gauge C-3292, or equivalent in place at accumulator port.
3. Move Gauge C-3293-SP, or equivalent over to front servo port for this test.
4. Have helper start and run engine at 1600 rpm for this test.
5. Move transmission shift lever two detents rearward from full forward position. This is D range.
6. Read pressures on both gauges as transmission throttle lever is gradually moved from full forward to full rearward position:
- Line pressure at accumulator in D range third gear, should be 54 - 60 psi (372 - 414 kPa) with throttle lever forward and increase as lever is moved rearward.
- Front servo pressure in D range third gear, should be within 3 psi (21 kPa) of line pressure up to kickdown point.
