New Member here. Found the site when I was researching the Chevy Shake. I purchased a used 2015 Silverado just before the end of the year. Beautiful truck....I've waited so long to get. The first week I owned it I was in town all week....never going over 50mph. Since then I have started back traveling for work and I am shaking all over on any speeds above 65. The console vibrates and its unbearable. I have 34k miles so I am still under the factory warranty. I also purchased the extended warranty to 90k miles. I am seeing drive shaft and torque convertor as the most common fixes. Would you just ask the dealership to test drive and try those fixes? Sounds like that might be met with resistance. Thanks for any advice
