I got the engine and transmission removed from the frame!! Only missed one hose, which was a coolant line coming from the overflow tank. I learned some things - first was that you can get stainless steel carabiners (or similar) that can hold 1800 pounds, which work really great to hold the load balancer chains to the lift rings on the engine. Second, since the engine and transmission weigh about 750 pounds, its best to stick the engine hoist out there - mine is rated for 1-ton, and I set it at the 3/4 ton spot. I wish I would have put it at the 1/2 ton spot, because when I lifted the engine up high it started to rub on the hoist itself.
Once out, I was able to take off the two little plates that have to come off in order to separate the engine and transmission, and since both are present I will assume that the transmission has never been removed from the engine.
The transmission is still stuck to the engine, though. I got some MAPP gas and tried heating up the area around the stuck bolt, but that wasn't successful. I can get quite a large gap (1/2") on the passenger side, and a small 1/8" gap on the drivers side, so it's definitely just that bolt. I also tried using an SDS hammer drill set to hammer mode to try and punch out the bolt, but that didn't work either. This damn bolt is really stuck in there!!
