I searched the forum before asking this question...and I didn't come up with anything. I have a TH350 in my '66 Chevelle and I'm a pint low on fluid. The tranny was rebuilt about 2K miles ago and it has a very small leak. I wanted to ask what fluid I should be using? I'm seeing so many different types on the shelf and I'm not sure what's in there now. Should I add any oil?? I've heard of this but have never done it. Thanks in advance for the info/help.

Dexron III is the fluid you need.

Thank you.

Yup, that's all I ever use...
