Slight bump when downshifting to 3rd

[dajsho]

I have noticed a slight bump when downshifting to 3rd using paddle and only to 3rd. Upshifts are all smooth and downshifts to all other gears are smooth. Has anyone else seen or heard of this?? Stock 2015.

I'm having a similar problem lately in my 2010 running a livernois stage 4 plus tune. But mine feels like it's slipping for just a second, smooth in every other gear. I'll shift from second to third and the rpms will rise about 2-300 rpm, then go back down.
Will have the dealer check this when I take it in for my 75k service next week

Yes...I have a 2015 SHO Stock non PP 8,500 mIles - 4th to 3rd downshift is rough....it went to the dealership last week for an oil change and they checked it out...they ended up reflashing the tranny so it is now in the process of relearning my driving style...which I would call spirited...I actually haven't had it in sport mode yet so I am not sure if the rough shift issue is still present...I will let you know what I find. The dealer said if it persisted or got worse to bring it back....although I am not sure what they would do at that point.

You don't need to be in sport mode. While in "D" you can downshift and when you get to 3rd it will shift rough. Let me know if the reflash helps.

Ok...after allowing the reflash to settle in and relearn my driving "style" I went to Sport mode and went all out track day style driving on the hilly curvy back roads of WI pounding the paddles, the tires, and the pavement. First off I fully understand that you can use paddle shifters in either forward gear...however I really do not use paddle shifters unless I am in Sport mode...good news is that the clunky 4th to 3rd downshift issue that I was having is now gone after the tranny reflash. The only time I ever had this issue previous to the reflash was when I was using the paddle shifters in Sport mode and 4th to 3rd downshift was harsh, no matter what the RPMS were. Reflash it you'll like it.
