I didn't touch the transmission at all other then taking the 5 bolts out of it to take the transfercase off. Didn't touch anything in the engine bay either other then replacing the battery. Thats why I'm stumped. I really don't know why it would do this.
Is there a possibility I put the transfercase back together wrong? That its stick in low the whole time. I did have all fours up and put it in 2wd and only the back tires spun though. And in 4lo all four spun.
Edit: Is it possible that the helical cam or ramp its called has broke or came away from the fork and is stuck in 4lo but when I switch the button inside the shift motor is thinking its turning it to 2wd but is actually shifting it to 2lo and not knowing showing everything is normal? Far fetched but I'm not totally sure how all this works. It feels like I'm in 2lo is the best way to explain it.
And when I turn the switch between 2wd to a4wd and to 4lo is there supposed to be any sign of it coming out? My dash light changes fine, no flashing or anything but feel or hear anything.
