I have some chugging issues between 20-40 mph and it's not throwing any engine codes. Recently changed cam sensor bank 1 and everything worked well for a couple of months. Any thoughts?

 

Does it feels like the transmission grabs and tosses you back?? If so, then it's your solenoids in your transmission. There are 3 of them and when it gets dirty with metal filings and they stick, when they unstick it slams it into that gear.

IMO, if your Mech say you can removes your transmission pan, the Solenoids and clean them yourself. Do know, the Transmission oil for the car is expensive, but it sounds like that needs changing anyway.

Or, you can just buy them used or new depending on price and swap them out. Just make sure you take a picture of the wires before you take them out.

 

I appreciate your thoughts, more intel on the situation: We also just replaced a coil as well. It typically does not do this until after it has warmed up for a while, guessing 15 ish miles, and only between the 30-40mph range (wife corrected me on the range, lol). So with all that being said, your thoughts make sense to me. I did speak with the Manager of an Autozone yesterday and his thoughts were centered around changing out the spark plugs?
