[4l80 slipping in 3rd...NEED HELP!]

Hey guys we did a 4l80 swap in my brothers 04 single cab. Before doing the swap the tranny got new clutches and a transgo hd2 shifkit. When we got the truck tuned it slipped in 3rd. It shifts into 3rd but instantly starts slipping. Any idea on what could be the problem? Thanks in advance

[Procharger P1SC1 removed from 6.2 NEED HELP!!!]

Guys I need help with a procharger question. I have a 2004 silverado with a 5.3 and would like to know if this procharger coming of a 07-14 escalade 6.2 will fit without buying new brackets. Also what injectors would you guys recommend? Thanks for your help I don't want to buy it and find out it won't work.

[SS bumper brake ducts for sale $120]

I have a pair of front brake ducts for sale. Price is $120 including shipping. Both ducts have a missing tab but can still be secured easily. They don't have grills in them and will need to be repainted as the previous owner painted them black. I found a complete bumper and no longer need these. I was gonna keep as a spare set but willing to sell. These are getting harder to find and ridiculously expensive. Cannot upload pics at this time but will email or txt you a pic if interested.
