2013 Ram 2500 6.7. Turbo back 5 inch and anarchy tune as well as transmission tune. Bone stock except that. I installed everything Monday and have been driving it everyday. I haven't been hard on it at all. Waiting on the transmission to smooth out and relearn. Question is, it starts a slight shaking ( almost like a tire out of align, grabbing feeling) at around 1800 rpms. It's just before the transmission shifts gears. From 35 to 38 mph range. Then at 45, 55 , and just steady cruising around 75. I feel like it's the transmission, but may could be something in the motor tune. Transmission is still all over the place with shift smoothness and firmness. Great one time, then horrible the next. I've called Anarchy two days in a row. They haven't got back with me. It's very irritating to drive right now. Any ideas?
