Just received the new flush talked about here Bulletin No.: 18-NA-355 and so far so good. But this is my 5th time to dealer for the shutter. 2 years ago did a flush worked for a bit, shutter returned. Then new torque converter. Next year new blue label Mobil 1 Synthetic LV ATF HP fluid. We will see.........
The funny thing when I took it back this time the local dealer said it needed new transmission. I said OK. Later that day they said not one transmission to be found in the US so we will rebuild this one. I said OK. The next day they said well our transmission guy left dealership and working somewhere else now so we need to send your truck to our other dealer 20 miles away. I said OK. That dealership called and said we will do our own diagnoses. I said OK. The next day they called and said they had found the Aug 2019 bulletin on the new oil and so far so good after 20 mile test drive. After driving home after picking up I did notice a huge improvement but need to drive 200 miles for the full effect. Fingers crossed. I am only 10k from going out of warranty or 3 months. After reading this forum I am not to sure about this.
