Has atf4 superseded conventional power steering fluid on 1st gens? Link for refernce please. Cant find info yet on this bit of info. Parts store says no but I dont trust them. I'm going to be doing a system flush next week and will go with whatevrs best. Worst comes to worse the dealer should know eh?

 

Sorry no reference. But I don't see why atf would be used. Not that it necessarily couldn't be used, but I can't think of why they'd just switch to spec ATF instead of P/S.

Just standard power steering fluid is what I use. She steers like butter.

I'd be interested to know if the dealers says to do something different.

 

on gen 3 at least, its in the owners manual from what ive read. Figured I'd ask here.

 

Ah okay I wasn't aware. Personally I'd use P/S fluid for your truck but sorry I don't have any info on whether that changed, all I have is the FSM.

 

I just used PS fluid in my build...no problems so far.
