This has been happening for a few months now, no shop has been able to solve it.
So far the clutch, actuator, carrier bearing, 3 speed sensors on the transmission and accelerator pedal has been changed and it feels like after they just changed the carrier bearin the jumpin shaking has gotten worse.

It happens intermittently which is why I believe the dealers can't solve it. This video is from this morning. After sitting for 48hrs I warmed up the truck placed it in low and moved about 300 feet, set my brakes went to check in at the shipper. When i got back in the truck hit D and boom threw my coffee everywhere. Its been happening mostly in 1st or 2nd gear. If i speed up to 4th, it'll stop until it decides to do it again. It also sometimes happens when i stop at a stop sign or traffic signal. When it goes into 2nd gear ill feel a slight bump then when i start to accelerate it shakes or jumps violently.
When this happens it feels like the accelerator pedal is super sensitive, lately there has been a lag feels like i have to push it further down to start moving even empty, but when this shake happens the slightest touch it makes the truck feel like its on steroids or something, itll move 40k like its nothing.

Also i feel like I need to add that if the truck is parked over a week itll work just fine for about 1000 miles then itll start with the jumping and shaking in 1st or 2nd gear only other gears work just fine.

If anyone can help or has encountered this issue please help me out. I keep taking it to these shops and they just keep replacing parts and nothing seems to help. Took it to 2 peterbilts 1 kenworth and a few local shops who ends up telling me i need dealer... idk what else to do.
