Steering: Service Precautions

NOTE: Automatic transmission fluid should not be used in these power steering systems. ATF is not compatible with the seals and hoses used in this system and will eventually cause damage. Also, power steering fluid must withstand very high pressure (about 1400 psi), whereas transmission fluid does not have the need to operate at these pressures. If a ATF has been added to a power steering system as in an emergency situation, the system should be drained, flushed and refilled with power steering fluid as soon as possible to avoid damage.
