First Hemi - Not sure what is normal or not

[TreyBobo]

Hello everyone. I picked up a 2019 Ram 1500 Bighorn with the 5.7 Hemi about a month ago and loving it so far. Since it's been 15 years since I've had a V8, it feels night and day different from the little Camry I had been driving so I'm not sure what actions are normal and what are cause for concern.
Not being the original owner, I'm most concerned about the transmission being abused, so every little thing I hear or feel is concerning.

1. When it is cold, it seems to shift from Park in Reverse or Drive a little rougher. The truck seems to lurch a bit going into gear. Don't notice it when the truck is warmed up
2. Sometimes when driving, it seems to bog down a bit like it's in too high of a gear. Not sure if this is caused by the MDS kicking off or on
3. When cold and rolling at idle, it seems to bump itself along instead of rolling smoothly. Might just be a crappy Oklahoma parking lot?

Thanks for looking at this. I'm sure I'm just being paranoid, but would like to see if others have seen these things. It's only just over 31k, so I can always take to the dealership if needed.

Could be any of those, could also need a reflash. Ask the dealer.

unplug negative on battery for at least 15 min to "reset". Also use gear selector to eliminate MDS..keep in +8

Issue #1 are you letting the idle come down to normal before shifting into gear?

Let her warmup alittle longer for #1 and possibly #3.

#2 that very well could be the MDS kicking in and out. You'll notice a slight 'thump' and the exhaust note will change whenever it engages / disengages.

1) Sounds normal. These idle pretty fast initially.
2) That sounds like your ecu has you in geezer mode, where it takes a lot of pedal to get it to kickdown and/or accelerate. Try shutting things off, then power on without foot on the brake so all the dash lights come on, then slowly press the gas pedal to the floor and slowly release it. It seems to relearn things when you do that. It costs nothing to try.
3) Activate the ECO light if you haven't yet and see if it corresponds with the bump.

Hey that's how I drive... Geezer mode. ...then slowly press the gas pedal to the floor and slowly release it.
Everyone behind me is gesturing "RAM is #1" or something like that...

That’s exactly what is happening. Thank you!
