power steering pump problem

Mopars don't use atf, they use power steering fluid, which hydraulic oil is a great substitute for and a lot cheaper.

ATF will make the seals leak and doesn't have much lubricant to it flush the ATF out and put in PS fluid or hydraulic oil.

When these cars were built from my understanding there wasn't a difference between ATF and "Power Steering" Fluid
ATF will help with an older system to keep the seals swollen up and keep from cracking
