(issue: not shifting from first and speedometer not working) I have a 2003 avalanche 5.3 4l60e 2wd, swapped motor and everything was going fine until i realized it wasnt shifting and then i saw the speedometer wasnt working (all other gauges were though), i did live data to see if it was reading and it read 0 MPH also. so far ive replaced the sensor with an ac delco one and it didnt fix it, just seeing if anybody out there had a similar issue before i have a chance to keep looking for the issue again
