I just bought a 2021 trailboss with 12,000 miles. the window sticker says 5.3 ecotec3 No autostop, How do i know if i have DFM? i am leaning towards that i dont have it because my build date was summer/fall of 2021 (i think, i need to double check), i just wasnt sure if there is a sure way to know?  also i found in my carfax report that i had to sign to purchase the truck (to varify that there were no recalls) that the lifters had been replaced at 8000miles (never mentioned by the salesperson either).... i guess thats good that they were replaced but i question if they failed or was it preventative?

      How to Tune 6L80 Silverado transmission

      By ballencd · Posted

      New to this forum.  Also looking to tune a 6L80 and trying to work out all the issues in my transmission swap.  I have a 6.2 diesel (1983) and have removed the TH-400 and about to put in a 6L80 with a TCM-2600 interface and don't have a clue what I doing after that.  Did you (Leatherneck/RAV3) get your slip resolved? I too hate to spend that kind of money on a tuner that hopefully I will not need too many times although from what steelerdude15 added about the HP Tuner being great for diagnostics would be a plus.  I am also from WNC but below you in Columbus.  Any helo would be greatly appreciated.

      Sounds like a smart reasonable person with common sense. Bill O’Riley never said he was just a journalist, by the way.

      It's like saying Bill O'Reilly is "just" a journalist.         Lauren Fix, widely known as "The Car Coach," is a prominent automotive journalist, television personality, and self-identified conservative. She is a frequent contributor to right-leaning networks and platforms, offering commentary that intersects the automotive industry, consumer economics, and conservative political perspectives. [1, 2, 3] Media and Commentary Network Contributions: Fix serves as the National Automotive Correspondent for Newsmax and is a frequent guest on Fox News and Fox Business. Video Platforms: She has contributed to PragerU, where she has hosted videos critiquing government mandates on vehicles. [1, 2, 3] Core Positions Anti-EV Mandates & Fuel Policies: Fix regularly critiques government subsidies and mandates for electric vehicles (EVs), framing them as impractical and burdensome to the average consumer. She advocates for consumer choice and supports traditional internal combustion engine vehicles. [1, 2, 3] Economic Analysis: Her commentary often emphasizes the impacts of fuel prices, inflation, and federal regulations on drivers. [1, 2, 3] Political Alignment: On her public channels, she actively supports deregulation, "drill baby drill" energy policies, and the removal of government restrictions on auto sales and manufacturing. [1, 2] For analysis from Lauren Fix on how consumer automotive choices can align with political leanings:

      AFM Disabler Question

      Wouldn't swapping out the original AFM/DFM parts for a complete Delete Kit be the best route to go if one could afford to go that route?

      It comes with directions but yes, generally, it's the same.  Also, get you the dipstick stuff to install dipstick so you have one.
