Hello EagleMark thanks for the reply!
Yes Dave has been cool he probably was having a bad day.
I changed the fuel pump to the one from the C3500 HD so that's OK I adjusted the lbs per hour to the value in the 7.4 bin.
By "correct parts" are you referring to the 7.4 memcal? it has 4l80E info in it. can I still use it with 4L60E?
I tried to get codes a few days ago but could not get them the CEL just stayed constant. I'm a newbie not even sure what LHM/netres is can you explain?
