Can ATF+3 be used in the power steering pump? > If not, does anyone know the difference? Is there a preferred power steering fluid? > > 300ly, > Mark Lindahl > Barrington, IL > '63 300 Conv. Manufacturers post volumes of product information on the internet. Valvoline site has product information on their power steering fluid. We use it and it is marketed as Pyroil Power Steering Fluid. We use power steering fluid for all units that do not specifically state to use only transmission fluid and for all the units I have seen that factory recommendation has always been limited to Dexron specifically. Honda and some others require a special fluid and not Dexron. Class 8 truck steering systems require Dexron. Note in the fluid marketers data that power steering fluid is intended for power steering only (and specifically not automatic transmissions). The literature I have seen for more than one power steering fluid product states that the stuff will help prevent leaks. This normally means that the stuff has ethylene glycol in it's chemistry. The recommendation we got from Steer and Gear was steering fluid as mentioned but I do not know if we ever had a brand recommendation. Note that data for transmission fluid makes no mention of suitability for power steering. We do know that older Chryslers had Type A fluid from the factory which has developed, evolved into the Dexron spec today. Power steering fluid or Dexron in the old units I think will work quite well. Trying the newer Chrysler spec ATF+3 or ATF+4 might not cause any problems in the old units but why risk the chances and what would be the purpose?
