Help I screwed up and added

How much did you add before you noticed?

Probably time for a flush and fill anyways.

What does power steering fluid do to an automatic transmission once you added it?

Rob.

The same thing automatic fluid does. Not to worry

Probably nothing as they are very similar, and AFAIK your particular transmission isn't all that finicky about what you feed it. However you might as well drop the pan and change the fluid and filter; it's good PM and then you won't have to worry about it any more.

I can't comment with 100% sure about on PS in the AT, but I know that most car manufacturers reccomend using the auto trans fluid in the power steering. My sense is to get a bottle of transmission fluid, top off the steering, and call it a day.

A vehicle transmission is typically 6 quarts, so 12 ounces of similar fluid isn't hurting anything. Now, I can think of a few fluids that would worry me, but PS fluid is OK.

If it was a problem at all in the first place.

For some unknown reason years ago my daughter took her car to Wal-Mart for an oil change. They filled the brake fluid, only problem is they put power steering fluid in it. About 6 months later the fluid turned very thick almost like a gum. The entire system had to be replaced. Of course Wal-Mart denied any wrong doing. We didn't push the issue. It was a very costly mistake.

I can see that being a problem. There are a few others which would be a real mess, but I don't want to give people ideas.

PS fluid is made for larger tubing (1/4 or so) and is a lot heavier. I can well imagine it clogging the narrow brake lines.

That's different, brake fluid and PS fluid are very different, however PS fluid isn't that different from Dexron...

The only thing that I can think of at this time is that the power steering fuild may dilute the distict gripping properties of the transmission fluid. Better to be safe than sorry, change out the fluid.

Baloney...... PS fluid is a petroleum based hydraulic oil. Brake fluid is ethylene glycol based (same as anti-freeze) and the two don't mix. The eventual result would be a system ruining jell.

Brake fluids, commonly, are water soluble polyols. Tranny fluids and power steering fluids are oil soluble...

Now, when you mix water and oil intimately, you get.....mayonnaise... You should have sued the bastards

I think I agree with RSC. A tranny is a very costly repair. If there is so darn much difference between Chrysler fluid, Dexron, and the like, then I dont see power steering fluid as being welcome in my tranny.

All I know is it turned to jelly.

I don't like ATF in the power steering, sure, it's cheaper, but I've seen too many cars where the steering box pitman shaft seal leaks after adding ATF. As for the transmission, PS fluid is hydraulic fluid, so is trans fluid, so I don't see it as an issue.
