I'm taking mine in tomorrow (22 with 2800mi) What i'm experiencing seems like a torque converter issue but I'm not sure. Main issue is I have a vibration when coming to a stop all the time when trans is warm. (put it in neutral, doesn't do it) Then right around 50mph I start feeling a harmonic vibration in the pedal and wheel till I get to higher speeds it seems to fade with road noise etc.... By harmonic I mean that.......it is lighter, heavier, lighter and back and fourth and you can hear it audibly. But it just keeps doing that from about 50mph up to higher speeds like 70 or more and then I can't tell. I'll let you know what they say on this ok! I also am going to have them balance my tires but I'm 100% sure its not the tires the frequency is too quick. I am going to see if they have a vibration analyzer I would like them to test a few spots to see if it's heavier versus lighter in one place or another. Thinking on the trans, rear diff, front diff etc...to see results. I also feel like it could be a driveshaft balance issue as well as I have experienced this in older vehicles. Let you know!
