We picked up our 2019 Ram 1500 Hemi almost exactly a year ago.
Once the weather started cooling down I noticed that it has a pretty significant hesitation, or pause, or even a hiccup when pulling away from a dead stop when the power train is cold.
My wife drives the truck most days, so I didn't notice this right off the bat, but it is very consistent. If I start the truck in my driveway, and pull down the block to the slightly uphill stop sign, the thing will start to roll a bit when I start to pull away, then fall on its face, and eventually recover. I'm not sure if it feels like a torque converter or clutch issue in the trans, or like some goofy throttle programming going on.
If I put it in tow/haul mode it does it to a much lower extent, and once the trans was warmed up over 100 it was nearly non-existent. I initially thought it was related to cold weather when I brought it in the first time, but I'm bringing it in again today for the same issue during the dead of summer.
When I brought it in last fall they started with a power train module flash, that I think was related to the acceleration "bump" that folks were reporting last year.
When I had it in a few weeks ago the tech confirmed that it was happening, checked that the software was up to date, and told me he could not do much about it beyond recalibrating the throttle pedal and throttle body, which he did. He did mention that there is not a check valve in the torque converter for this trans, and it can drain out fluid when shut off (which I'm not totally sure I buy - this is a super common and well regarded transmission).
Anyone else experience this, and have any luck finding a culprit?
I actually got a phone call from Ram Customer Care today asking if I had issues, because they noticed it had been in several times for this issue.
Thanks all.,
