2016 GMC Sierra SLE with 5.3

 

in 2021 the transmission self destructed 

this time... it's the DOD giving issues.

 

Last June I had the truck reprogrammed to disable the DOD on the computer.

Over the last few weeks i've had a check engine light with rough idle code.

 

today when I pulled into the driveway, the check engine light was flashing.

 

 

So now the search begins... who around Oklahoma City can honestly and correctly replace the parts to forever correct this one.

 

 

Currently sitting with 120xxx miles.

Pull the code and see what is going on first, you could save a lot of $ and time.

If it isn't broke don't fix it just yet unless you have a bunch of extra cash laying around.

Compression test and leakdown test first.  Could be a simple as a broken valve spring which can happen on these.  

 

Worst case, the cam has a lobe that's wiped bad.

First things first, get the codes read.  It might be something as simple as a bad coil pack, fouled plug, bad 02 sensor, etc.  I would hate to assume I have to tear down an engine without even knowing what's causing the issue.  If you do wind up tearing it down, its an easy enough job, you can do it in your garage with the engine in the truck if you have a decent tool set.

      2027 GMC Sierra: Official Discussion

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
