Maxlife means it swells the seals, then when they wear more they"ll leak again. It does not mean it will make it last longer like metal parts in a motor using Mobil1 for instance. As soon as you get into using maxlife, high mileage oils, etc... that's when seal swelling additives are in the oil. That goes for any fluid for any component.

I wouldn't worry about the ATF+4 in the PS system.

I guess a good rule of thumb for high mileage fluids would be if it doesnt leak, there is no need for a high mileage fluid with a stop leak additive. Correct?

Correct..... And your steering box is leaking because that's what dodge ram steering boxes do anyway. LOL

I know that is what Ram steering boxes do, but it went from no leaks to being covered in PS fluid in 5,000 miles. I wanna blame the fluid...Uh I mean my, stupidity!

No updates to this thread? On a '97, PSF should be the only fluid used, even for a flush?

With the price of ATF+4 why would you want to use it in the PS system?

I'm in Canada, so in winter, thinner is better. Just don't want to cause other problems. The TSB is kinda hard to understand. A little contradicting it seems.
