where at in the harness do i need to look? i took the plug off an tested for continuity and it has it but haven't checked the other end of the harness and i searched for a speed sensor fuse but couldn't find one. i replaced the sensor still hasn't changed and still throws the code.

Heyyyy so my 2000 jimmy is doing something very similar, by chance is you abs and parking brake light on? Mine did this and the first time once the speedometer started working and lights shut off it shift just fine. Now it just doesn't work. Just curious, did you ever fix your problem? I can't find what it is.
