Problem Description and Possible Solution
If you experience rough shift and/or shuddering during gear shifting, software updates to the powertrain control and transmission control modules (PCM and TCM) are available which may address these problems. On higher mileage vehicles, a mechanical failure may exhibit similar symptoms. Proper diagnoses should be performed before any repairs or software upgrades are attempted.

My 300C has a jerky transmission which is very troublesome. IT always occurs at a slow full stop and sometimes its noticeable in acceleration from a full stop. Everyone who rides in my car notices it.
I have taken it in to two dealers 4 times and am always told there is nothing wrong with the transmission and had it in to an independent auto shop with the same conclusion. My car has very low mileage (8000). I love everything else about this car and it's my third 300. This problem did not exist for the first 6000 miles and it has since taken some of the joy out of the car.
The drive shift would not change to the next gear. Car would not go over 20 mph and check engine light along with
ABS/BAP light would not go off. Dealership updated software last year and still the PCM went out this week. Dealership changed PCM for 490.00. I think this should be under factory warranty.
Car won't shift automatically when rpm is high. Engine light on
My 2010 Chrysler 300 will only start. When I shift into drive or reverse the car acts, as if it's in neutral. My lights, radio and other electrical comes ON just fine. One person, said the problem could be inside the transmission or some kind of update it needs in the computer. As of now, my Chrysler is still sitting in a shop broke down.
The car shakes/shutters around 40mph. After a while the car would not shift after 3rd gear. My lights started coming on and off on their own as well as the AC did not blow cold air either. I let the car sit for a while and had to call AAA to jump start the vehicle. The AAA driver advised needed new battery. Once he put the new battery in the car ran fine for a while and the problems all cam eback. Brought it to a machanic and they think its the computer.
My 300 AWD betan "surging" when arriving at full stop... upon stopping, the transmission would "surge" by taking a "push, or leap" then coming to a stop. Only doing so when cold at the beginning of the day or when sitting for a long time. Dealer "flashed" the computer and the problem was solved... however, before the "flash" and the "surging", this transmission was the smoothest shifting I have ever experienced... had to look at the tach to see when it shifted. Now the transmission does not "surge" when cold, but shifts like a truck. Warming up stops this phenomenon.
I now have 10, 290 miles, and the "surge" is back, only it is now when warm, and occurs periodically. Maddening to say the least.
shifts hard and has had repeat problems with being stuck in second gear.
Software updates did not repair the problem!!!
I have a 2013 Chrysler 300S. I noticed this problem when test driving, but thought nothing of it because it was cold and had been sitting for two months. More recently I'll start the vehicle in the morning and allow it 2-5 minutes to warm up. When I take off in Drive, things seem fine, the RPM''s just rev a little high in idle speed and when starting to pick up speed. After I stop However, I'll start to go again and then I notice the RPM's getting high before shifting. Also, If I let off the gas when this happens I hear a low groaning noise (Not to be confused with a grinding noise). Within about 30 seconds or less the problems goes away an I can recreate it. I contacted my used care dealership and they told me the cant service it or even evaluate it until the Engine light comes on. They need those codes in order to determine where to start looking. I, on the other hand would prefer not to have the engine light come on and/or get stranded before I get my vehicle looked at. I called a Chrysler dealership and they said that there is a software update for my vehicle, but that it has noting to do with shifting when cold. They on the other hand said they would keep it overnight and take it out in the morning to try and recreate the occurrence I described above. Would anybody have an Idea of what could be going on here?
It's impossible to come to a smooth stop. When shifting into low there is an abrupt 'jolt' (as if someone has bumped into the rear of the car). Has been to the dealer four times with valve replacement and computer flashing. Problem is still not fixed! It may be 30% better but it still does it 70% of the time. It's a new auto, should be 100% as one would expect with a new auto!
When I reach 80 mph the drivetrain shudders... bump bump bump bump really hard. I also am experiencing a severe loss of power when this happens, and sometimes when I am trying to climb hills. Car seems pretty weak at times.
I just bought this car had 41000 on it when I bought it. After having it a few days I've been having the car sure at low speed. Hard shifts. Also when going down hill car seems to surge as well down shift real hard
I have had the same problems listed here since I purchased the car. the dealership acted like they didn't know what it was. They flashed the computer and it continued to happen after a few days time. There was never a resolve for the "push/surge" forward. Now my car stutters, won't go over 20mph, and a whole plethora of other problems that the dealership can't figure out.
Shudder or vibration around 40-50 mph. This car shifts into overdrive before 40 mph. I believe that it should shift into OD above 45. Will go after the PCM/TCM software update. 3.5L V6, auto.
Trans shop diag it as torque converter clutch. est $890.00. Dealer stepped up and diag it as trans. Replaced it and reprogrammed PCM/TCM and did a relearn all for free. All is well. Chrysler sales managers can get stuff done.
Hard shifts when engine is cold, had into dealership this weekend, they did software update, I still have the problem. Mileage is correct as listed - 2,700
Surging during shifting and when braking. Dealer has examined the vehicle and claims that there is no problem, advises use of higher grade gasoline to solve problem (that, according to the dealership, does not exist).
Shudders when changing gears
I had this problem for 3 weeks now. I bring it into the Chrysler dealership they said there is no software update for my particular VIN number. I have a 2015 Chrysler 300 limited all wheel drive. I only had it for 9 months. I noticed when the vehicle is cold the transmission shifts hard from 2nd to 3rd gear. I have not experience any lights come on the vehicle.
2008 LX 2.7L Chrysler 300 that will have hard shifts when driving over 40mph.
the car feel like it running over some speed brakes then it shift hard.
