Ok guys i really need help. My 2006 silverado z71 with the 5.3 has started making a clicking noise almost like a bull dozer on the pavement when pulling out, also makes a roaring noise when at speed and the throttle is let off. So i figured it was the pump rub problem so i pulled the transfer case and it had been rubbing some so i bought a kit from merchant auto. I put it in and put the transfer back in the truck and put 5w20 full synthetic in it like most guys have been going too. So after that i started my truck and and pulled out and the abs and brake lights came on and the truck wont shift out of first gears. I really need some help guys. Any suggestion??
