it drives fine once you hit a steady speed and the transmission will seem like its trying to go into overdrive or something. like it drops to the lowest gear possible and i have to hit the throttle to get it to downshift and speed up real fast. and when its in overdrive, it seems like it kicks in at too slow of a speed

cruise control doesnt work. im getting power to the switch on the column, im getting 12v on just the ignition wire at the module but no 12v to anything else when braking or setting the cruise control. some go from like .05 - .11 or something like that

brake light comes on at around 35mph. goes away when truck is restarted

ive checked the brake switch on the brake pedal and it works. what does the button on the other side of the brake pedal do?

one plug under the master cylinder (small box thing with 2 plugs in it, abs module im assuming?) has all 12v accept 1 wire.

the other plug has nothing.
