2019 GMC Denali 1500 with 8L90 transmission SHUDDER WHEN SHIFTING! Feels like a misfire!

Today we have a 2019 GMC Sierra 1500 Denali that has the 8 speed transmission that has a shudder when shifting. Per GM TSB we don't need to replace the transmission! I was unable to buy the correct tools for the job due to no inventory anywhere so it became a messy job but we got it repaired! Thanks for watching!
