Acura RL (1996-2004 year). Manual — part 437
Pressure Testing
• While testing, be careful of the rotating front wheels.
• Make sure lifts, jacks and safety stands are placed properly (see
).
CAUTION:
• Before testing, be sure the transmission fluid is filled to the proper level.
• Warm up the engine before testing.
1. Raise the front of the vehicle, and support it with safety stands.
2. Set the parking brake, and block rear wheels securely.
3. Allow the front wheels to rotate freely.
4. Warm up the engine (the radiator fan comes on), then stop and connect a tachometer.
5. Connect the special tool to line pressure inspection hole.
TORQUE: 18 N-m (1.8 kgf-m, 13 Ibf-ft)
CAUTION: Connect the oil pressure gauge securely, be sure not to allow dust and other foreign particles to enter the
inspection hole.
