Transmission might be fried. One suggestion, did you try putting it in 4WD and trying that? I had a Jeep come in, same thing, wont move, ended up being a blown transfer case. Put it in 4 hi or low, and see if it will go into gear and move. Long shot, but worth a try.
The loud screeching sound is from the serpentine belt slipping over the pulleys a little. You probably got some radiator coolant on the belt or pulleys when replacing the radiator. When you connect both battery cables the alternator is trying to charge which puts a load or drag on the alternator which causes the belt to slip over the pulley enough to cause the screeching. The only way to correct this is to take the belt back off and wash it with warm soapy water to remove the coolant contamination from the belt. Then scrub the pulleys also as coolant was transferred from one pulley to another by the serpentine belt. Then replace the belt and put a little comet cleanser onto the belt to extract a little more of the contamination from the belt and pulleys before you start it up. And last but not least make sure the belt has the correct tension so as to prevent it from slipping. If you wait to long the belt will always be contaminated and forever screech. Do not buy any belt dressing for the belt. That stuff is junk and makes the rubber in the belt soft and leads to a premature belt failure.
Your water pump is starting to seize up. Today's modern serpentine belts don't just slip. Your water pump is dragging. Which is causing the noise and the temperature increase. Get it fixed and you will notice better gas mileage. If you continue to run it like that be sure to keep your eye on the temperature gauge. One overheat or close call has the potential to do big damage to an engine of that age.
May be a weak tensioner that needs replacing. Make sure you clean pulleys well with brake cleaner or similar as well. I have had one with similar problem, that Gator back belt was causing it. I'm not 100% convinced that a notched belt will get as good a grip as a complete rib all the way around the belt. Just doesn't add up to me. If you compare that to tire grip, then you'd be telling me that snow tires would work better on the Nascar circuit?
i would suggest checking to see if you are getting fuel by disconnecting the fuel line at the fuel rail and turn key if no fuel then its either fuel pump or fuel filter. if you get fuel then it would be the spark
