2016 5.3 6 speed. Do these trucks have learning transmission programming that adapts to the driver? I've gone easy the first 2 months and now the tranny seems much less responsive and resistant to downshift than week 1. If it did learn my driving, if you stomp on it for a few days will it downshift quicker?

The word from the dealers is that there is a learning process involved with transmission programming. That may be the case in some small way. There may be some routine that fine tunes the base program. The funny thing is, I didn't experience any learning mode when I applied a Diablo tune to my transmission. The change was immediate and for the better. So I'm kind of skeptical about this "learning" mode thing. I'm not sure whether the transmission is adapting to the owner or vice versa. Anyway, to address your question directly, don't baby the truck. Drive it like you normally would and after 5000 miles or so, if it isn't right take it in for service. Trust me, you wouldn't be the first.

The 6 speed in my '14 acted weird in learn mode, but after about 2-3,000 miles it started to act fine. Since then it's been perfect. Some can take a little longer from what I've read.

There are some adaptive tables in the TCM that take some time to fully set in. I don't think those tables can be wiped from a battery pull, I believe it takes using a Tech II in order to clear them.

It seems that some transmissions are unteachable. Especially ones assembled wrong or with defective components. :rolleyes:

      Of course refrain from political debate but I myself have very dismal hope for what is all going on up here every where we turn so I nodded my head when I saw this joke.

      Wow I'm in a pickle. (Broke down truck) and a story.

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.
