I have a 2020 AT4 with a 6.2L. I have had all my scheduled services done at Beck and Masten GMC in Houston, TX. My truck has 74k miles on it. And it has been making a strange noise from under the truck. Took it to Mac Haik Chevrolet as Beck and Masten service went down hill. Was told my transmission pump was failing. And also told my transmission has NEVER had the fluid changed which was due on my scheduled service at 45k miles. Even though I have been getting my services done at GMC!!! So I'm being quoted $7,640 to replace the transmission!!!! I can not believe a fairly new truck that has been serviced and taken care of now needs a new transmission because the GMC dealership I trusted it too never did the work that was recommended by the manufacturer!!! This truck will be going to my son next year and I will not be buying another GM vehicle if I can not get this resolved. Nothing makes me more pissed than to be put in a position where I have zero recourse even though I did my part. PATHETIC!!!!
