I already changed the vehicle speed sensor supposedly there is one inside the transmission that’s attached to the valve body I changed the one on top of the transfer case and the other guy did both of them and that didn’t fix anything

mountainmanjoe

changing parts didn't fix anything? Shocking.

Did you figure it out by chance
