Hello ! I have a 2016 Peterbilt 579 with a auto eaton ultra shift plus transmission. When my truck is pulling heavy load and I start accelerating from zero after a red light or a stop sign, it starts jerking. It feels like the transmission is slipping. The RPMs goes up very quick and then come back. I see rpm gauge bouncing up and down. This keeps happening until the truck get enough momentum or say pass speed 50 km/h. When this happens I have to let go the gas paddle and then press gently to avoid it. But when i am going uphill, letting go the gas paddle is not an option. It won’t happen on a level road if I be very gentle on gas paddle but it happens even on level road if I press gas paddle hard. Please let me know if anyone have similar problem. I am a new owner operator.

Soumds to me someone needs to learn how to feather the pedal... How much experience do you have driving truck? This isnt your sedan that you can just mash the pedal to the floor.
