I recently had a stage 5 PPE kit installed in my 03 LB7, put the transmission back in the truck and I wasn't getting any pressure to my lines. Pulled back out taken back to the shop after replacing everything electrical on the transmission and checking the internal filter and was found the converter relief valve was stuck open. It was "fixed" and put back together. Now I'm getting no pressure whatsoever out of lines or pressure port. I'm tired of dealing with this and being kicked around on what's wrong. Any suggestions? Also the only code being thrown is P0701. And anytime the truck is put into gear it says "range shift inhibited"
