I have a old 90 Caddy that is forever leaking power steering fluid. Well we were out checking the fluids on the thing and my brother grabbed the wrong container and filled the power steering reservoir with about half a quart of transmission fluid! Will it hurt it? Do I have to drain it? Will it just leak out over the next week like it usually does with no harm? Advice desperately needed! thanks.

It's about the same thing honestly. Pretty sure they're interchangeable.

Some you can some you can't. I don't know about yours but my 89 F150 I used to put ATF in the power steering.

It'll be fine. ATF and PS fluid are pretty similar fluids anyway.

I wouldn't worry about it. The Land Rovers I work on spec Dexron as power steering fluid. It will be fine.

Relax... your caddy will be fine.


On that car it's interchangeable.

Now if you had a Honda it would be a different story. But older American iron will take it just fine.

My 07 Mustang and 00 Crown Vic both use Mercon ATF in the power steering. However, if you added ATF into the Cobalt's power steering or some of the newer cars then you're in trouble because modern power assist systems are not hydraulic. My SS/TC has an electric motor in the steering column that provides the assist, sort of like a force feedback wheel on the PC or PS3.

I don't mean to highjack your thread but since the answer seems to be that it will be ok, I have another related question for the hive. I have a power steering leak on my 96 cherokee also. I am wondering now if tansmission fluid stop a leak could be used in the power steering?

Why would there even be a reservoir for hydraulic power steering fluid on a car with electric power steering?
