Transmission downshift shudder/ jerk issues

I seem to have a transmission shudder / jerk when hard braking causing the truck to lunge forward in a hard braking condition.Who else has this issue? The reason i ask is that this is a safety risk when braking in traffic.

 

I have this too, I've always believed it was engine braking but it's kinda random and more harsh at some points in time.

 

Mine shudders when downshifting from 3-2 or 2-1, like I'm riding over a rumble strip. I can feel it in the floorboard, seat, and the steering wheel the most.

It's a 2wd so the TSB doesn't apply. I had it at the dealership last week for this, they replaced the rear drums and sent me on my way. Obviously that didn't fix the problem but I didn't push back any since I got new drums out of it. Will be making another appointment in the coming weeks.

 

Mine is doing this too. 2017 TRD sport 2WD. Any thoughts on cause of rumble strip vibes

 

I'd change my vote to yes if I could. Wasn't sure exactly what was being asked here, but I do get the rumble strip feel. Honestly it hasn't annoyed me enough to look into trying to fix it or worry about it.
