Transmission issues/promblems?
Yeah typical stealership saga. See at the very least what plugs they change and what brand. If its a cheapo brand I'd just bite the bullet and redo them all. But I would walk back in with a handful of new plugs and say "ok I'd paid for the plugs can you PLEASE just change out the rest of them of me since I just dropped thousands on this truck". maybe they will do it however you did get a lot done the last time with no warranty they may just tell you to shove it! Hope you get it all worked out! Keep us informed
While you doing the mass MAF did you do the throttle body? Its only a couple more screws and will really help low idle problems. And re clean both of them again in 100 miles with that oiled filter. The oil with gunk up pretty quick after every filter cleaning and give you problems. I've had the gotts mod and a square style K&N for like 70k miles and have had no ill effects once I learn to just clean everything after 100 miles after doing the filter cleaning. Before I learned that I started having low idle issue caused by filter oil. Lemme know how she runs once all is done I'd be curious to see if she runs a lot better for you!

No it takes only like 30-45 min to clean it all. Go to the late model section then under the model year choices there is the how to section open that then open the engine section and "cleaning throttle body/MAF is the first how to Section. it's really easy basically e same as the MAF just make sure you clean the butterfly valve really good
One of the main reasons is the butterfly won't completely shut because its gets gummy there for letting more air than optimal for the fuel mixture causing it to run poorly at low idle. Also when the walls gum up it will upset the air flow patterns leading to air drag and again another cause for inefficient air/fuel mixture.
