CammedL83

@superdave160 thank you, I definitely will check over bolts. My tuner doesn’t do a whole lot of tuning with transmissions. One of his suggestions was to take it to dealer and have trans reflashed.

Need some help before spending tons of money. Recently did the AFM/DOD delete and cam swap (BTR Stage 2) on my 14 sierra with the 5.3. This was a couple months after having my trans rebuilt. Everything seemed fine before the cam swap and after the trans rebuild. Or at least thought it did. After many hours with tuner saying that truck had idle problems, problems dying after starting then shut off then trying to start back. And problems shifting when hitting the throttle. My tuner says my trans is slipping upwards of 1000rpm in a 1/10 of a second. As well as some spark delay. I find it hard to believe my transmission is messed up after just having it rebuilt. I did not upgrade the torque converter to a billet. It had a slighty better than stock converter installed on rebuild. Was done by a reputable shop. I also believe the cam just doesn’t chop as much as it should in other videos I’ve seen. I’m stuck and not sure what to do. Plz help!
