View Full Version : What type of trans fluid?

09-20-2008, 07:00 PM
We are getting the 83 C-3 automatic rebuilt, (again) what is the correct type and amount of fluid to refill?

I don't want to run it low or with incorrect stuff. One book I saw said Mercur 2, but I've read various thread opinions on that topic?

Also I want to purge all the old fluid from the lines, converter and radiator/cooler. Any suggestons on that (force it out with an Air hose?).

And finally is it preferable to fill up the converter prior to putting it in the trans and trans in the truck?

What I've read:
stock Converter holds just over 4 quarts
stock c3 holds 8 quarts
Does this account for the lines and radiator/cooler?

83 Ranger 2.8V6 2wd, thanks in advance.
Just helping out a young friend.

I would suggest a rebuilt converter as well. If not it should have a drain plug. All the older Fords did.
I would run dextron III or better fluid.
The only "wrong" fluid is the cheap, dollar store, ATF. It will work just fine with type F as well.

It does have a drain plug in the converter and I got 4 qts out of it.
Looked really nice and shiney blue so I'm guessing it isn't the original converter and has been replaced. Thanks for the info on Dextron III.
