I have a 6.5x14 trailer and I hauled 35 sheets of 1/2" 4'x8' osb last weekend on it and thought I would try tow/haul on my 2018 and I noticed it made some of the downshifts pretty hard, like jolt you into your seat belt hard.
My 2018 isn’t FF either and I ran one tank of E85 in it and had the symptoms as the OP. I am going to order the sensor and tubes soon to convert mine over. Sent from my iPhone using Tapatalk
I am really interested in this as well for my 2018, especially if the sensor is auto detecting because I don't plan on tuning my truck until after the factory 60k mile warranty is out but I want to be able to run E85 in it while towing.
It’s well after it goes back to v8. My truck is a 6spd with 3.42s. Once it downshifts into 5th it’s fine, it’s just the time before that when it’s trying to hold itself in 6th. It feels like a dead miss but I really think it’s transmission/converter related. Sent from my iPhone using Tapatalk
I’ll pay attention to that over the few days. I have ran 4 tanks of gas through it so far. Whatever the dealer put in it when I bought it then 1 tank of e0 91, 1 tank of E85 and now back to e0 91. Sent from my iPhone using Tapatalk
I have had my 2018 LTZ 5.3/6spd for 9 days now, its my first GM product since 2012. I see lots of people on here complaining about the stutter during acceleration but I am seeing it a little differently. I drive 50 miles a day on the interstate at 70mph. When I hit hills it will switch seamlessly from v8 to v4 and then at random times it feels like a dead miss a couple of times and then it will normally downshift and then its fine the rest of the way up the hills. It is really driving me crazy for a brand new truck to be doing this. I love everything else about the truck but if it keeps this up I may light it on fire.
I just traded my 17 Ram Big Horn for a 18 LTZ and the only thing I really miss is the power of the Hemi/8spd/3.92 combo vs my 5.3/6spd/3.42 combo. It got crappy due mileage and rode rough compared to the Chevy. One thing I noticed was that there were 2014 1LT trucks on the lot with 50k miles that were worth more than my 2017 Big Horn with 36k miles.
I have had mine for 8 days now. I scrolled past it a dozen times on their website thinking it was black but then when the November incentives came out I went and looked at it and was super happy when I saw the actual color. Sent from my iPhone using Tapatalk
