I just did the same repair but havnt tested them yet.

Not fast at all. I had it in M1 or 2 and slinging about 25mph trying to keep rpm up. I’m going to try upload a video.

Has anyone been able to figure out their truck temperature fluctuating? my 2017 GMC 5.3 will climb up slightly without towing in mountain or steep pass when towing it will get as hot as three-quarter mark. Also, my truck will start going into some kind of lint mode or something. GMC checked it out and said they were unable to duplicate the problem and that the cooling system was working as designed find it hard to believe.

Did you figure it out?
