    Default 07 malibu transmission fluid mistake / issue

    Alrights guys, got a good one here. My sister has a 07 malibu and she accidentally put power steering fluid in her transmission reservoir. i know, super dumb. But, now idk the best move to make next. Tow it / drive it to garage and flush trans, possibly replace any gaskets etc? I'm not a trans guy at all, so any help / would be appreciated.

    I would take it and have it flushed. Although the ps fluid may not harm anything immediately, it does not have the same properties that trans fluid does. It expands at a different rate. Lubricates differently. I would have it flushed and new trans fluid installed asap.

    Yeah I advised her to flush it asap. Thanks for the info/quick reply pikey.

    No heartbeat, unfortunately she managed to put ps fluid in the trans lol.

    Ya know, I'm not going to go against what the others have said, but I was wondering how much did she use?

    Both are hydraulic fluids. ATF will have some dye and some additives for longer product life and better lubrication. The ATF is a superior product. But if only a little PSF was added, the net result would not really change the properties of ATF.
