No TC lock up or OD

Hey guys, have a couple of questions regarding my transmission. I installed LED tail lights and load resistors, and LED front running lights. After this, I didn't drive it for several months. I have it back on the road now, and I'm stumped. My ABS light is on, no TC lock up, and no overdrive.I have removed the LED bulbs and the load resistors completely and put the original bulbs back in, and I still have hyper flashing and ABS light with transmission issues. I looked at my third brake light over the weekend, and the middle socket for the brake light itself was completely melted and corroded and the bulb was melted. So, I tried replacing the bulb and it worked for the first time since I've owned the truck. However, after I did that, when I would hit the brake pedal, my dash lights and front running lights would come on as well . I took the bulb back out, and now it stopped, but I still have the initial transmission issues. Could a short in the wiring for the third brake late be causing this? I never had these problems before I installed the LEDs, but now it won't go away. My VSS has already been replaced. Not sure if this makes any difference or not, but I have had HIDs for about two years, and I have LEDs for my front running lights as well, but I was told I would not need load resistors for those. Any input would be greatly appreciated!

The only place where the parking lights and brake lights are "close" to each other is the lights in the bed. If you have the bulbs installed incorrectly, or the wrong bulbs, the two circuits can cross and the brake pedal will turn on the parking lights, and the parking light switch will turn on the brake lights.
