Pressure Test With Transmission In "1" (1st Gear)
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 1996 Dodge Ram Wagon, 1996 Dodge Ram Van, 1996 Dodge Pickup, 1996 Dodge Dakota, and 1996 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
- This tests oil pump output, pressure regulation, condition of rear clutch and servo hydraulic circuits. Remove pressure tap plugs and install pressure gauge in accumulator and rear servo pressure taps. See Figure . Start and operate engine at 1000 RPM.
- Move manual selector lever on transmission fully forward to the gearshift "1" position. Read pressure on both pressure gauges as throttle valve lever on transmission is moved from fully forward position to fully rearward position.
- 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. Rear servo pressure should be within 3 psi (.2 kg/cm2 ) of line pressure.
- If line pressure is not within specification, adjust line pressure. Refer to the LINE PRESSURE under HYDRAULIC PRESSURE ADJUSTMENTS. If proper line pressure still cannot be obtained, check for defective components and hydraulic circuit. Remove the pressure gauges. Install and tighten pressure tap plugs to specification. Refer to the TORQUE SPECIFICATIONS .
