no tension when tightening trans. pan bolts

[JBeysolow]

I've had a terrible time trying to get transmission drain pan bolts on. Car has leaked ATF after sitting overnight.

Symptoms are:
1. Although bolts turn and seal pan, I am getting no tight fit. Bolts are gaining no resistance (torque) after a certain point. (I've unscrewed bolts and no stripping apparent on grooves)

2. Once I started car noticed leaking between passenger side bolts (middle bolt and bolt closer to enginge)

3. Upon waking this morning and looking under car, about 3+ quarts of ATF leaked overnight.

This has happened after drain of torque converter, transmission pan, and replacing trans. filter.
