Major Trans Problems

[Chevy1TonFun]

Ok so first off the bolts for the trans to the transfer case adaptor keep coming loose, even after torquing them. Second, with that come leaking ATF. Third problem went for a drive, after thinking I fixed the problem, to find that I still had a leak. So we turned around to go back home. We stopped to pick up some ATF and 5 miles from home the trans gives out. Even after filling it up with more ATF it won't engage into gear. So she got towed home. So after all that, my question is what is shot, the trans, the torque converter, or both. My money is on the TC and maybe some damage to the trans. I'll have pics later.
