Can you use 10W-30 oil in Fluid Drive?

Couldn't find the straight weight 10W here in FL, so had to put this in.
Will it be alright? Won't damage the converter or the seals? Seems to
drive OK, just wondering.
Thanks

 

fluid drive what?

what trans?

 

Seems like it should be better then the straight weight stuff.

 

You must not know that Chrysler made the Fluid Drive transmission from
1938-1953. It consisted of a Fluid converter with a four speed manual.
Two ranges(First/Second) and (Third/Fourth). You used the clutch to move
between ranges/reverse. To change gears, you simply got up to about
20mph, lifted your foot off the accelerator, then it would shift. Put
your foot back on and go! I have a 1941 Windsor with the vacamatic
shift, using a vacuum cylinder to shift between ranges. It required a
special oil, no longer made, but it is like 10W engine oil. I was just
asking if 10W-30 would be acceptable for the straight 10W, which is very
hard to find.

 

well there lots of heavy equipment and trucks that use a transmission name
like that so i had to be sure what trans you were referring to. we ran 10
weight Kendall in the hydraulics in all the loaders back in my gravel pit
days years ago, and used straight 30 weight in the transmissions. but again
that was heavy equipment.

if there's a oil distributor in your area they can usually supply a single
weight oil if you need it. your only issue might be can they get the 10
weight in qts or only gallon jugs or barrels. i was buying a synth blend
oil by the case, buying it here http://www.newsomoilcompany.com/

 

Chrysler used to make this available for industrial use and marine use,
so it is possible they were the same thing! Even steamships used a
variety of Fluid Drive.

 

Damn! What the heck are you driving?!?!?

I found this, though it's not much help. One guy suggests hydraulic oil:

This link recommends 10W motor oil:

You can get single-weight 10W here...

Hope you need 5 gallons!

Shell has Single-grade Rotella 10W oil available. I would try to locate a
well-stocked Shell dealer or distributor and try to get some of that.

Good luck!

 

A beautiful, all original, 23K four door Chrysler Windsor, 245ci flathead
six, vacamatic fluid drive and all the options you could use in 1941!

 

Damn! A Battle Cruiser!

23K?!?! Man. I bet it WEIGHS!

 

Of course I meant 23,000 miles on the odometer! Yes, that is my car,
those twin four door sedans look just like mine. That guy maintains
great Chrysler pages with great personal recollections to go along with
them. Have seen his postings many times over the years. Are you in
Japan? If so, are there any old Chrysler cars over there?
