6 speed downshifting

Mknipp · March 23, 2020

I have a 2018 silverado 5.3 6 speed with 31,000 miles. While driving I will let off the throttle to coast before I use my brakes. I can feel the transmission down shifting and I can watch my RPM's go up with each downshift. It feels like downshifting with a manual transmission I was just wondering if it's a normal thing.

Yes. Normal.

Try putting it in tow haul and the downshifts are a little more aggressive IMO.

Well it agitates me severely but I read using a tuner and do a torque delete is the remedy. When my powertrain runs out I'm setting up the idle I know that.

Yep, normal. Why wait? BlackBear tune is not detectable by dealer.

I didn't know that but now I do. Thanks!

A dealership can see the flash counter if they wanted too. It doesn't matter if it was HP Tuners, EFI live or something else. They can't see what exactly was changed but something is shown when the computer is written.
