My 2008 Nissan Xterra will not start at all, we tried to jump it off but that made the battery cables get very hot. Right before this it had no power at all. It did not want to go?/Could that be the trasmission?

What is your question?

A few days before it would not start, I had to get it jumped off then a few mins after driving it the windshield wipers came on, all the lights lite up on the panel, it didn't have any power at all, I kept mashing the gas but it was struggling to go. We thought the cable wires were loose. Tighten those up, it was ok , next morning, needed jumped off again.. Drove good all day. No problems. That night we left our home, again no power, it didn't want to go, I kept mashing the gas, it would barley go. Once we got home and turned it off, waited a few mins and tried to start it back up but it wouldn't start up again. Tried jumping it off but that just made the battery cables get really hot. Pls help me. Does this mean the transmission is gone???

What makes this problem better or worse?

What " was " making it better was jumping it off or charging the battery but nothing works now. It won't start at all
