Powering Steering Fluid VS. ATF

Powering Steering Fluid VS. ATF
Last summer, I installed a CarQuest rebuilt power steering pump on my '92 F150. It is the C-11 pump. My Ford manual says to use a Premium Power Steering Fluid E6AZ-19582-AA (ESW-M2C33-F) or equilvalent on the C-11 pump. I flushed and refilled with CarQuest Type FA automatic transmission fluid per my local Carquest dealer's recommendation. On the back of the CarQuest Type FA ATF bottle, it states that this fluid meets Ford specification (M2C33-F) and therefore I believe this is why the CarQuest dealer recommended this fluid. The pump works fine and is not noisy at all. Am I in error in using this ATF fluid in my power steerring pump? Is there a difference between a power steering fluid that meets spec (M2C33-F) and an ATF fluid that also meets (M2C33-F)? Thanks, Charles

ATF will be fine in your power steering pump. Auto transmissions and power steering pumps are both hydraulic pumps. The reason for specifics in ATF for trannys is because of all the other goodies inside the case besides the pump like bands, clutches, diaphrams, seals and gaskets. Some of these will deteriate if the wrong type of ATF is used. The power steering pump has a couple of seals and hydraulic hoses and a gearbox. All components of these systems are pretty much bullet proof with minor maintenance. That is why most agricultural eguipment rely on hydraulics. Any type of hydraulic oil will sufice in the steering pumps.
