2018 Ram shifting problems

[J-Ram]

I bough a new 2018 Ram 1500 a few months back and have started to notice that when i am driving slow the transmission takes forever to figure out that it needs to shift to a lower gear which causes a bit of vibration. Is this something that is common with these trucks or do i need to get it looked at? Its not terrible but it is enough that it seems like its a problem.

Has it gone through the learning phase ?

If you have 3.21 gears it will probably seem a bit laggy when the MDS is engaged especially at lower speeds since it has a tendency to engage way to early IMHO. I would try driving with it disengaged and see if it helps. I always disable mine when I'm in slow traffic, stop and go situations.

It can't hurt to have the dealer check it. They might have an update for it.

I'm not sure about the vibration, have the dealership look at it. As for the slow speed shifting irregularities my 2018 6.4 does the same thing. I usually lock out a gear or two in manual mode and it helps a lot.

Honestly sounds like MDS to me

Next time you drive the truck use the gear +/- buttons to disable MDS and see if it still happens.

Thanks everyone. I did turn off the MDS today and the "problem" is gone. That MDS really makes the truck feel like its stuck in to high of a gear for to long. Almost rather it not be there. I dont recall having this feeling in my 2015 Big Horn.

Yeah its scary because it almost feels like torque converter shudder, which makes me...shudder...because Im always paranoid about my automatic transmissions grenading.

On the highway the feeling is much less pronounced, but in city driving it feels laggy and like the truck is in too high of a gear. Without MDS on in city driving the 8HP is actually quite responsive, so its not the transmission causing the issues.
