Transmission Issue? Calling all 15 SRT owners

So I have to go to the dealer in a few weeks for cosmetic issues, and am wondering if I need to say anything about my transmission down shifting from 6 to 5 rough while in auto. Researching the issue I am finding mixed reviews with some saying it's normal and others saying theirs do not do it. So I am asking 2015 owners, does yours have this issue? Thanks for any input!

Re: Transmission Issue? Calling all 15 SRT owners

It's not just the 15's. I had the same issues in my 14 and just had them resolved a few weeks ago with a trans flash at the dealership. Night and day difference in upshifts and no more horrible (try to throw you through the windshield) to smooth and buttery.
Mine downshifted rough from 6-5 ,4-3 and then 2 was the roughest.

Re: Transmission Issue? Calling all 15 SRT owners

my trans is fine as far as I am concerned....yeah, it's not as butter or "refined" as my '14 Summit Hemi (exact same trans) but I feel it is aligned with the performance aspect...it is predictable and pretty consistent so nothing stands out as a problem...fwiw, I do believe the '14 had/has a higher incidence of clunking/harshness in certain downshifts from what I read...

if you were built March 3, 2015 or earlier maybe this TSB is the fix...seems to sniff around your 6-5 down issue...if yours had the S27 recall done then I think this was automatically done as part of the required TCM flash for that "shifter" recall...

Re: Transmission Issue? Calling all 15 SRT owners

Yeah mine was built 10/2015, so no TSB or updates. And yes it had the S27 update already done when I bought it. I guess I will have them take a look just to see if they can find anything.

Re: Transmission Issue? Calling all 15 SRT owners

On my 15, when I'm about to come to a stop I feel a hard jerk forward, sorta like getting kicked from the back. It only happens sometimes and I can't quite pin it to the transmission or if it's the mds kickin in.

Re: Transmission Issue? Calling all 15 SRT owners

I drive mine in sport mode 90% of the time and have nice firm downshifts. Even in normal mode they are firm but not as hard. It's programmed this way for a sportier feel and probably for the longevity of the transmission. Does anyone remember the shift kits that you would install in the tranny? It would slam the gears. I don't remember if it was to save the clutches or what. If you want butter smooth transmission get a summit or an overland.

Ask them to perform a transmission "Quicklearn" with witech and see if that changes anything for you, as long as you are for sure up to date on your TCM software level.

Mine was doing that, like it wants to throw you into the windshield. I was going to install a 5pt harness bc it downshifted like an F1 car. I barely needed to brake bc the gears were stopping me plenty.
It's normal now though.

Re: Transmission Issue? Calling all 15 SRT owners

My first 15' was a mess. Awful downshifting. Replaced torque converter, valve body, trans, rear end, both rear half shafts and obviously all the software updates. Still had a terrible downshift. It was bought back and replaced with a new 15'. The new one has been flawless.
