I agree with most of the posts above, but here are some comments:

Like they said, the computer needs time to adjust(shift points both up and down, etc) and 177 miles isn't enough time to do that. The computer is "adaptive" and will learn and get better each time it makes a shift.

As far as the gas tank, this can't be your problem as the gas tank issue is only after completely stopped. Also, I personally think the 32 gal tank without baffles is a bunch of BS, and not the problem. I believe it is the hill start assist that causes the "clunk" after stopping. I had the HSA on and sometimes when I stopped I'd get the clunk. I turned HSA off about 1 year ago and haven't had the clunk since. I believe what happens is after stopping the truck's wheels rotate backwards ever so slightly(due to the weight of the truck shifting) and the HSA senses this and applies the brakes. I believe the clunk is the brakes.

Can you describe your "shake" a little better. I'm wondering if it could be a warped rotor(only happens during braking) or if it could be a wheel/tire out of balance(only at certain speeds), or maybe you're feeling the transmission adaptives as others have mentioned.

Also, don't worry about people who say dodge has junk transmissions. Since the 45rfe(early 2000's I think) all their transmissions(trucks, anyway....not sure about the cars) have been great. The 45rfe and it's whole family, the same as in your truck, hold up great. People who say other wise either are going by the bad rep dodge got for their transmissions in the 90's or abuse their trucks. Adding 200hp to your engine and damaging the transmission is not dodge's fault, it is designed to handle the power that it is bolted to, can't blame that on the manufacturer. I've had several friends with hemi rams that added mods and drag raced their trucks for 100,000+ miles without any transmission related issues. I actually don't know anybody with a 3rd or 4th gen ram that has had transmission related issues, and I probably have known 20 people with rams over the past 10 years. Most of these guys drive hard and drag race.

Give it time... These are very high tech trucks!
This is true^ I know plenty of 4th gen rams 2011+ who will disconnect the battery say the weekend before we all head to the track, and every day that week heading to work and out running around will drive with the pedal to the floor. By the time we get to the track the truck has learned around that full throttle driving habit, and it nets them a good 1/4th+ second faster in the QM Times hah!

I have to agree with most of these guys. My truck had 9 miles on it when I bought it. I didn't baby it at all and it has always shifted pretty smooth. This may sound crazy, but after about 5k miles it seemed to have more power. As far as people saying the transmissions are weak I don't buy that. I heard the same thing about my 07 Charger R/T and after 57k miles it still shifts as good as new. My wife drives it pretty hard sometimes, but so far no issues at all. I think yours will probably smooth out soon. Oh yeah I almost forgot to say welcome to the Z.

Fuel slosh would not be just one clunk....it would be one big clunk, followed by one or two more less impactive "clunks"....liquid doesnt stop on a dime...ask any trucker who has hauled a liquid load.

(I am now also wondering if the HSA is behind my issue -throttle control light comes on and trucks stops when climbing a gravel hill in reverse in 4wd lock...system gets confused.)

I should have mentioned also I'd get the clunk and don't have the 32 gal tank. I turned HSA off long ago and haven't had a clunk since.

Might be. Try turning it off and see if it helps.

For some reason, when replies are being made on a thread I created im not getting the notification email anymore so I didnt realize the responses! As much as I could not believe it myself, I do believe it is the fuel slosh! When the tank is completely full the "quick multiple vibrations" do not happen! As soon as I start leaving the full mark I start feeling them again, not as often but do. Ram has called me to see how the truck is since purchasing it and have stressed to them I am very disappointed in this. We are currently playing phone tag to resolve the problem, but I refuse to let them start breaking my truck down. I will keep all posted and thanks again.

Got my truck a month ago and was happy go lucky until my wife got in and noticed a vibration and pointed it out to me. THANK YOU HONEY!!! I have OCD and things like this will drive me nuts until I figure out what is causing it. Figured I would at least put some break in miles on it. Had 3 miles on it when I picked it up. Vibration seems to be gone now at 500 miles. My next move is to not let my wife ride in my truck. Problem solved.

Welcome to this RamforumZ

As was mentioned, the Ram is really Adaptive, it is learning about you, as you learn about it
The ABS pulsations, the Traction Control, the MDS system, & the Transmission are learning to work together.
I don't use MDS in the city, it feels & sounds very strange at low speeds, like 27 - 35 mph
I too believe the little bump at a stop is the Hill Holder Assist, not fluid movement, but i still look in my rear view mirror to see who bumped me, it only happens between 1/2 & 3/4 tank of fuel & that is the strange part

Mine does this too. I live in Texas with NO hills. I still get this THUD when I stop my truck I noticed this when it was half way full. I filled the tank and it still did it once I came to a quick stop. VERY frustrating...
