I'm asking because I have an unopened quart of Valvoline synthetic power steering fluid. Anybody know any reason why I couldn't use it. I'm sure it will mix with the ATF4 but don't want to cause any harm. Thanks

 

so are you wanting to use the power steering fluid in the tranny, or the other way around?

 

ReDone, he is wanting to use power steering fluid in his power steering. but the rams power steering uses ATF4. personally, if it were me, i would use what the manufacture calls for. there must be some reason they use it, and i wouldnt want to mess it up using anything else.

 

I think you're right. I'll just put ATF4 in.
