6.0 hesitation

[Targa1us]

My 2017 Hesitated a couple times. I usually run regular gas, then I ran a tank of Premium gas thru it.

No more hesitation....actually I picked up a little better mileage. I back using regular now and still no hesitation.

My 6L90 had a very slight shudder in first gear, part throttle start-up.  Over a week it got more noticeable.   Yesterday, at three lights in a row, the trans flaired- up on the 2-3 up-shift.  Ordering a reman trans tomorrow.  Clutch material on the dipstick.   Watch out for the internet remans, a lot of bad reviews.  Came down to Jasper or GM.      Two days to get the GM reman.  215,000 miles, 100,000 miles towing.

Make sure it gets a new torque converter at the same time.

hey if my trans lasts that long i won’t be complaining that is great - especially for so much towing!
