Help with Daily Driver? Please?

When you get it back running, what "I" would do is go ahead and do a drain and fill and new filter on the transmission and add a bottle of this: Transmission Fix
I sold a lot of it when I worked at O'Reilly and always heard back good reviews. As with any additive, it will take a little while to get worked in and see results. But it will improve it at the very least, unless it's just burned up.
