You should use Mobilfluid 424. Available at any mobil servo or 7 eleven. If you run dextron or other trans fluid the little pressure switch on the rack will continually fail and leak through the top electrical connector and your end rack seals will leak faster than usual. Same goes for BA/ EF AU2. The fluid is clear and not red. You notice a definite change in pump sound when you use it over dextron. Turning the steering wheel when running dextron the pump has that definitive whining sound. When running mobilfluid 424 the pump is almost dead silent on the whine sound when turning the wheel.
