Have a 04 lly with some transmission troubles, it seems like the transmission is in a limp mode, sometimes it shifts fine others times it doesn’t wanna shift at all it use have a range shift inhibited message but it went away, now the truck only functions properly when the abs light is on and along with some other beep in the truck not sure what it is, what do you guys think? Computer issue? Transmission ? I don’t see it being the transmission cause it shifts normally some days other days it won’t shift into 2nd / 3rd tcm possible? Also should mention that the truck was working fine but had a main seal leak so we dropped the trans and replaced the seal and since then that’s when the issue occurred, tested all the wires and they’re all fine, has anyone ever dealt with anything like this? I’m confused. No lights on the dash, only abs sometimes but that’s when the truck is working properly.
