Trans issues

Don't know if this is an issue with the trans or something else that I'm overlooking but wanted to see if anybody has had the same problems. I have a 2015 2500 hemi (of course) and the issue I have is when start off from a stop it acts like I have bad gas, in a steady acceleration it feels like it's slipping in the first couple of gears and you can hear the tone in the exhaust change. Another thing it does is on cool or cold mornings it takes a while to go into o/d. I bought this truck used with less than 30k and now it has 39k. Just want to see if this is common. Sorry if this doesn't make sense, I'm rushing to get it wrote before work

The OD shift when cold thing is normal as it's trying to build heat in the fluid as fast as possible. As for the odd feel taking of that's something to look into. Is this only when taking off or can you get it to do it around cruise speed when trying to lightly accelerate too.

The time it's noticeable is start off, also it acts up when slowing down to turn and getting back in the throttle it'll act like it's hesitant about going and then just go. Don't know if this is another issue but whole on cruise I can have it set at 75 and it doesn't matter flat road or hill, it will lose 3 or maybe 5 mph and then catch back up usually causing it to drop a gear to do it. I guess I should also add that it's lifted on 37" but has been calibrated.

Ok may be an issue in the trans do you have access to a scanner at all to get cvi numbers?

My brother has a scanner but I'm not sure if it'll read those, I'm taking it to the dealership Wednesday for a radio problem, I'll have them pull it if they will. I've let them check it out before but of course the tech said it didn't actually up with him, and they won't let them ride with me to let them witness it

Make sure you remove your tuner before going the dealer or you'll likely end up with it needing be reset.

It's not a tuner, the dealership I purchased the truck from just got a speedo calibrator for it after I fought with them for months telling them that I needed a tuner due to the 15 models needing a new or used ecu in order to change stuff to adjust for tires but I found out from somebody else that you could do a speedo calibrator but if I wanted to do a tune I would have to buy the diablo kit with ecu and tuner and that is around $1000, so the dealership got out of buying that for me.

Have you changed your gear ratio to match the new size of the tires yet? When was the last time the TB was cleaned? Get a Diablo tuner to calibrate for the wheels and use the 92 octane tune.

No gear change, I bought the truck like it is so I assumed it was good to go. I didn't notice it doing this when I first purchased it because it had factory exhaust, it's really noticeable with duals so that's why it became an issue. It did the cruise part issue from the beginning. I want a diablo tuner but right now I'm going through a separation from my wife so funds are very limited- anybody want to donate one just let me know
