ABS light, stalling, E4OD problem...

I bought the truck listed in my sig about two months ago and it currently has 177,000+ miles. After purchasing it I went through the whole truck maintenance wise and repairing things that were wrong with it. On christmas day the truck started acting up in two ways. First, on the highway it seemed to be over revved like it was stuck in 3rd. But if i pushed the O/D button it would rev even higher, so I'm guessing it is getting into O/D but the converter is slipping? The second thing it did on christmas day was stall on me. I pulled over put it in park and after 3-4 times of trying to start it while giving it throttle it started. The next day everything was fine, up until today. I got on the highway and the truck was doing the exact same thing, feels like it's in third but if I push the overdrive button to the off position it will rev even higher. If I accelerate on the highway it feels like it upshifts and the revs drop, as soon as I stop accelerating the revs come back up. It also stalled on me 3 times today with the same procedure necessary to restart it. I don't know if it's a coincidence but all the times that the truck stalled I was under a 1/4 tank and at a low speed(under 35MPH). The ABS light also comes on randomnly. I would like to be able to check for trans./ABS codes but I can't find a diagnostic port on this thing to save my life.

Things that may be of importance:
The truck has a new tach sensor, because the revs used to drop to zero and the O/D light would flash.

The truck has a new supply pump, because the engine was "making oil" and the pump was the problem.

One of the things I did when I first got the truck was a trans. flush. The tech said nothing looked out of the ordinary and he thought the trans. had "plenty of life left in it." There was also a sticker from a trans. shop under the hood, which would lead me to believe the trans. had been serviced before. The fluid is currently at the correct level and looks good.

I also replaced almost the entire brake system after purchasing the truck. Turned rotors/drums, calipers, pads, shoes, master cylinder, brake fluid flush, and everything is very well bled.

The fuel tank sending units and "jumper wires" were also replaced after I purchased the truck because the fuel gauges would swing back and forth when accelerating/braking.

I did some research online today and disconnected the batteries for 20 min. to try and reset the trans. ECU, but it made no difference. I also bought a can of electronic cleaner and di-electric grease and cleaned the plug for the tach sensor, all the plugs around the injection pump, the plug on the brake fluid reservoir, the plug on top of the pumpkin, and a plug(very dirty) that's on the driver side of the trans. and no difference either.

Any help is appreciated.

I just replaced the ABS sensor that's on top of the pumpkin on the diff. and now the speedo flutters back and forth like crazy and it still has all the other symptoms.
