Automatic Transmission Problem?

Automatic Transmission Problem?
So i noticed that my 2nd to 3rd gear change in manual automatic mode is fine, but the shift from 3rd to 2nd at a speed of anything above 20 mph is a little jarring. Definetly not smooth as, lets say I were to go from 4th to 3rd (and for reference example the rpm is at the same level from 4th to 3rd and 3rd to 2nd) So if im in 4th going to third i end up at 2500 rpm and its fine....but when Im in third going to second ending up at 2500 rpm, its mot certainly not as smooth. Anyone else notice this or think I should be concerned. Im not to keen on bringing my car to the dealership just so they can joy ride it for 20 min then say the cars working fine come back if you have any more problems. Thanks.

more like, worthless question.
The higher the gear the closer the gear ratios.
The lower the gear the more difference of ratio between the gears and the more of whatever you are feeling.
However, i have never drove one, as i try not to buy a new vehicle with a totally new engine or tranny. It is better to wait a couple years until all bugs are out. Why do you think Mazda failed @ 24 Hours of Rolex, Daytona!

I am one of those who viewed and didn't answer. I simply have no experience with this transmission.
It may seem worthless to you, but check back and let us know if you figure something out. We need feedback and your contribution can raise the value of the forum.

What they all said. The issue is with the gear ratios and the fact that regardless of the engine rpms the change for the transmission is much larger. It's the same thing with a MTX car. You can easily downshift from 4th to 3rd without much lurch, but go down to second, or heaven forbid 1st and you'll feel like you smacked into a wall.
Why are you downshifting it anyway? Yes you can engine brake by downshifting, however it does put a strain on the transmission, and there's already a system on the car which works really well for slowing the car down and which costs a great deal less to replace than the transmission.... that would be the brakes. I'm not saying engine braking is without virtue, because it is. It just doesn't need to be done all the time.
I'd suggest letting the rpms fall further before downshifting to 2nd, and give it some gas when you do. Alternately for general driving just slow to a stop and then change the gear and you'll be fine.

Well I appreciate and understand what you guys are saying...but let me explain further why I'm worrying...I've owned multiple cars that have a semi auto trans. For example one of them was an 04 325 BMW. Now when I say I'm downshifting barely i literally mean I'm down shifting the engine at around 1700 rpm to get into second as opposed to it automatically doing it around 1200. A 500 rpm quicker change should not result in jarring, especially when this system rev matches. I could shift in my other cars as high as 3500 in 3rd which would put second around 4500-5000 rpm ad not so much as a hiccup. I was just thinking a car built 8 years later would have a smoother transition of not at least comparable. Who knows maybe this is just how the tranny is.

Nice post, I believe my vehicle does the same on my 2009 3 HB. My automatic transmissions is not very smooth when shifting in the 20-40 mph range. I still have to figure out exactly where and what gear it is doing it at. I've only had my car for 3 days.
