No sir. For 2018, even with max tow a 3.42 is the top gearing. Most likely due to the 8 speed auto that shifts earlier and more often than my 6 speed did.

Just another here is what I have towed report. 2018 GMC Sierra 2wd, crew cab, SLT, 5.3 V8, 3.42 axle, 1948 lb. payload with Max tow pkg. Pulled my 8170# total weight 35' toyhauler about 75 miles on it's maiden voyage. It was a somewhat windy day, 15-20 mph, with my 950# motorcycle in the garage to move the hitch weight below the 1200 lb mark. Had a Husky Centerline HD 14,000 lb / 1400 lb tongue weight dist and anti sway hitch setup. It towed as smooth as my cargo trailer at half the weight. Truck was not struggling on my level Florida roads, at all. The truck and trailer were level with only an inch of sag, until I released the WD setup to back into the storage spot (not required but ground was not as level as road) and spot was soft. Then she dropped several inches to the eye. Just another example of what a real good heavy duty weight distribution system can do for your tow vehicle. I have Firestone air bags sitting in a box in the garage and I just might be returning them as they are not needed.

I actually read the back of the finance contract for GMF. It states that they "may" charge a $75.00 fee if paid off before 6 payments. Since my other loan will save me $51. a month, I could be ahead of the game after two lower payments even if they added the $75. to the payoff quote.

Thanks for the empathy,but, there is no fix yet. Probably why we have 585 pages on this forum thread.
