I'm Awesome
I have a 93 k1500 with 5.7, 4l60e. I just recently had the transmission rebuilt and it drove fine for 2 months after. A couple weeks ago my trans started shifting erratically and my park brake indicator comes on as well as the speedo goes crazy. It only does it about once a week, but makes it almost impossible to drive. I put in a new speed sensor and pigtail connector and thought it was fixed until today. I also tried another speed sensor buffer or drac but it continued to act up. I'm kinda lost as to what other wires I need to check. It does have a newly rebuilt posi rear end that I pulled from a 99 Yukon, not sure if this would have any effect
