Why would they tow it for this problem? The switch is in the latch assembly.We change alot of them.You can monitor the inputs to the BCM from the latch assembly with GDS2.If its a 2019 its covered under your bumper to bumper warranty, let the dealer fix it.

Gas or Diesel?

Don't waste your time with the 8 speed. Drive the 10 speed and you will buy the 10 speed. No comparison between the two.

To all the experts on here, the fluid flush does nothing to help shifting. It is only to remedy the shudder. I have had 2 2019 trucks already with the same problems as all the others. Both built after 3/1/19. The 2-1 downshifts will knock your fillings out, happens randomly. Good luck trying to get it fixed. GM ties our hands and doesn't want to pay for anything lately. I also made sure I bought a 6 speed in my 2017.

You will be living with those problems until you get rid of the truck. I am the transmission guy at a GMC buick dealer and you can't fix the unfixable. That transmission was horrible from the get go in 2014 and still keeps me plenty busy. Go drive a 10 speed and decide if you want to live with the 8 speed after the road test. Night and day difference between the two transmissions.Too bad you couldn't slip a 4l80e in all the problem trucks and be done with it.

The harsh shifting has nothing what so ever to do with the fluid exchange being done for TCC shudder.

The caliper brackets have much more problems than the actual calipers. Make sure the slides are free and the rust is cleaned from behind the abatement clips. I work at a GMC Buick dealer and we stock the brackets by themselves because we change much more of those than the cailpers.

Are the rear brakes actually working correctly? Infrared temp gun aimed at all rotors after driving will give an indication of whats going on. Fronts normally hotter than rear, should be roughly even between both from wheels.

I bought mine brand new in sept of 2017 and only paid 41,000. SLE with the snow plow package and navigation, and a bunch of other options.6.0 with 6l90.

Injectors leaking fuel

What code was it and why would they just clear and ship it?What dealer was it?

Power steering cooler.Common failure.

Have the dealer review PIT5206f, document ID#4875355. Exact symptoms you are experiencing.

Those tires are junk.

The first thing the dealer does is put in your VIN and run the history on the vehicle. You don't have to say a word and they know everything about that vehicle. Where it was bought and made and any open campaigns.Any warranty work done any where shows up as well.Try another dealer and see what happens, what have you got to lose? Sucks your regular dealer won't take the time to diagnose and fix it.
