I need some help with a 4L60e transmission. I had a guy rebuild it. He's a very reputable transmission guy. He is stumped.

1997 Suburban 5.7L. 130k or so.

He said the brake switch is reading constantly 12v. Something is not allowing the converter to lock-up and disengage properly. I believe that's how he described it. He replaced the brake switch. And now has replaced the computer. He is quite stumped. He's checking his forums. Any advice here? Any help is greatly appreciated.
