ABS Warning Light On and/or Erratic ABS Operation on Chevrolet Tahoe

The brakes were worked on but this problem still persists. ABS light on, sometimes steady, and you can hear them activating when first starting out. One time they seemed to 'lock'.
All four brakes locking down while driving. Engine in overdrive to account for the increase in resistance. Stopped at red light and smoke engulfed the area around my Tahoe. One of the codes on the computer says transmission is slipping. The vehicle is in the shop now... We shall see!
Around 5k miles ago the abs light came on. Now I know the cause

I talked to the Bosch engineer who designed the anti-lock brake system. He told me that one of the sensors at one of the wheels was defective - probably the LR. He said that was a comon problem.

There has been a recall for this (specific brands are listed). I just started having this problem and my tahoe is completely out of commission now until I can take it in to see if it was part of the recall. Fingers crossed.

The lights of ABS and BRAKE turn on 3 or 4 times a week, so, when that happens I stop, turn off the engine,and i start again, so they don't stay on

When I'm hitting the brakes, or slowing down on a turn usually within city limits, the brakes or the truck grinds essentially. I always called it growling at me. Then the brake light came on and it seemed like I was pushing my brakes all the way to the floor which made me think that I was using only back brakes. It is not currently fixed and I'm looking for a good mechanic that's easy on my wallet.
ABS warning lights comes on, and service brakes. Repair shop said the sensor is bad.
