It's still overheating. Overdrive is locked out something like five or ten degrees before the Trans Temp light comes on.
If your engine is running hot, the heat might be coming from the radiator as the engine heats its cooling system from which the energy is conductively coupled to the transmission cooler. But if the engine isn't overheating, then you've probably still got a restriction in the ATF cooling system.
I wouldn't suspect the pump, as it would likely manifest itself in a much grander fashion.

Engine isn't overheating, steady around 180 degrees. Should I be looking at the hoses that run to and from the radiator? Take them off and blow them out to make sure nothings clogged up?

If it were mine, I'd get a couple of cans of transmission cooler flush and shoot it through the cooler(s). Once against the normal fluid flow then woofed out with air at no more than 20PSI, then in the normal flow direction and blown out again. I'd just hit the hard lines, disconnected at both ends, with lots of compressed air. 90PSI if ya got it. Be sure nothing can be damaged should crud fly out! If you find gray gunk coming out when you flush, that's the good news -- worn off friction material tends to hang up in the cooler(s). If you don't get that gunk then the problem is elsewhere and the only other where is in the transmission itself.

so i come out of the bank today and see a puddle of tranny fluid under my truck, and trace the leak to this
is this the bell housing and is that hole supposed to be there? i'm guessing its a bad thing, so how would i fix it? and also could this be causing my issues? tranny fluid level is still in the ok range though...
and i also have another leak it looks like....
do i just take the oil pan off and replace that gasket to stop this?

Leaking from the little hole there (which IS supposed to be there by the way) is bad. Either the Torque converter seal is gone bad, or the pump is starting to leak. Either one requires dropping the trans.
On the pan leak, yeah, just drop the pan, and replace the gasket. Might even be as simple as tightening up the bolts a hair.

Thank you. I know I need transmission jacks and such for the drop, but should I just dish out the dough and take it to a shop? Also, wouldn't the pump going bad explain my transmission overheating? It is the only vehicle I have to get around in, but I don't want to drive it if it should be sitting still. I don't drive around much, so is it okay to drive it for a bit? I have been checking my fluid level and it doesn't really seem to be leaking much, except for when I came out of the bank today. Other than that, just a few drops here and there.

If it puked a puddle, it's only gonna get worse. If you don't have an alternate vehicle to drive, taking it to a shop is prolly gonna be your best bet. Be prepared for a 1200-1800 dollar bill though.... If the pump decided to smoke itself, it will distribute metal throughout the trans, and the rest of it won't be far behind in the 'belly up' attitude. You can try and limp it along for a bit, and see what happens, but, don't go far...... as you never know when it is going to simply stop working altogether.....
