It originally had a 5.2, swapped that including pcm. The front o2 was replaced (pretty sure I did that when I got it...might want to verify) and replaced cat and y pipe. 31.5x10.5 tires, nothing crazy, on it when I bought it. I have a code that popped up something to do with the evap after the swap, haven't dealt with it yet.

Hopefully I'm not showing my ignorance here, I've seen all the "don't tow in od" directives, but I kind of assume that meant "don't push it very hard in od". If I'm chugging along on flat ground with no headwind, I selectively have it od. I just feel that two quads on a utility trailer (granted steel not aluminum) shouldn't be asking that much. I've considered regearing I just don't tow heavy enough often enough to justify the cost.

Listen to Get you as he knows more about transmissions than I do. To test the torque converter, you can do the stall test. A common symptom of a failing TC is slow acceleration from a stop but good acceleration on the highway.

You can (wouldn't hurt) but just wanted to inform you it's not needed . It should be between the condenser and radiator.

I'm not there yet, but if I was to get a different converter what stall should I shoot for? Main use is towing 2-4k.
