Dextron and 30 weight oil are very different. Dextron can damage rubber
seals that are not made for that purpose.

I have been building racing automatic transmissions for 20 years.
They are FULL of rubber seals.

Dextron is made for automatic transmissions. It will not harm
rubber. It is made to be used with rubber.

I do not know what seal would be harmed by ATF, that the detergent
motor oil wouldn't...

Don't fret it, just empty the tank, fill it with 10w30 and in 5
years when you change it again, use 10w30.

Have you ever heard of adding a pint of trans fluid to an old Chevy
engine at oil change time? Stops hydraulic lifter noise...

Is there a petroleum engineer in the house?

Jay believe it or not there are seals that are harmed by motoroil. And
there are seals that are harmed by ATF. Jay there are many different kinds
of rubber seals.
I am sure you know that you cannot use Dextron in a Mopar product. I am
not saying it cant be done but I sure would not do it unless I was sure I
knew what kind of seals are in the pump before I put ATF fluid in.
Manufacturers give directions on what to use in their various products and
its best unless you are an expert on the subject (which I am not by a
country mile) to follow their directions.
This might shed some light on what I am saying.

It is our `83 PT35 that had ATF in the hydraulic reservoir. We took
it to Interstate Truck Service in Irving TX. They've taken good care
of us - hookups in the parking lot for two nights of free camping.

And now, that ATF is out of the hydraulic reservoir. We had them
drain, re-fill with 30 wt oil, then do it again. In the process they
spotted a leak in the hydraulic cooler - they put in a new cooler
unit. They showed us the `dead' one. Yucchh, the cracks were
visible, we could see how it was leaking.

So we're on the road again. Thanks to everyone for help with this
issue, especially Ernie for posting our problem.
