Default jerking when slowing down
So my truck has started jerking when I am slowing down. What would cause this? Transfer case going bad? Torque converter? Anything else?

Hmm. That's a new one. Not sure exactly what you mean by jerking.

Not when breaking. Its jerking like something is grabbing and letting go. It doesn't do it when I accelerate

Is it when your coasting and your totally off the gas(tb closed)? Does it feel like it's bucking or stumbling?

If this is your issue it is in the tune.

Mine does it as I'm slowing down from around 48mph-40mph without applying the brakes,Justin from BB told me it's my DFCO kicking in.

Yes, only when coasting. And it is more like a bucking. Been up for 24 hours and couldn't think of the work. What would I need to look at in the tune?
