2019 Colorado transmission shudder

[Tigstoy97]

Just curious if anyone out there is having as many problems trying to get the infamous Transmission shudder corrected as we have? 3 trips for the issue, now I have to leave the truck with no loaner or rental while we wait for the one and only transmission tech to look at it. Now because of their issue, I have to rent a car out of pocket while I wait, and the real pisser is that for some reason, no one else can at least perform the TSB fluid exchange to see if it will even help. GM so needs to be called out for this, sooooooo many tranny issues, and only allowed to have 1 tranny tech per shop.

 

Sorry guys & gals as this comes as a rant, but it kinda is. Bring back manuals if you can't fix the autos.

Try a different dealer.  Any Chevy store should do this possibly under warranty.  My flush was covered under the 5/50k power train warranty.

 

Use M mode and command 5th or 6th gear as the highest gear to use until you are at higher speeds.

Shudder flush procedure should be covered under 5yr/60k powertrain assuming you are within the 5 years or the 60k miles.  

 

Fixes 98% of the 8L90 shudder cases out there unless they've gone way too far on the older fluid (high mileage).
