I have a 2017 Escalade with 33,000 mile and i recently took it in to dealer beach=use the transmission was slipping between 20-40 mph. The tech called me and said that they put in a different type of fluid and that its now running good. However I’m concern since I saw on the internet that theirs a class action lawsuit regarding transmissions. Any suggestions out there I’m still under warranty and I dont want the transmission going out after warranty runs out
