Default May have a trans problem

Not sure if anyone else has this issue or not. Every now and then under maybe 1/3 pedal acceleration, 4th to 5th slips a little, and its always 4th to 5th only. RPMs just just a little during gear change. Does not do it under full throttle or regular normal acceleration. Anyone else have this issue? Car is at 55k right now.

I have noticed mine doing that lately as well. As you stated, it only does it on the 4-5 shift and only when putting around at very little throttle input. It never does it if I am giving it even around 30-40%+ throttle. I usually drive in Sport+ but don't switch until everything is properly warmed up. I notice it more easing out of neighborhood, i.e. normal mode, low speed, low throttle 4-5 shift.

What did the bolded part of your OP mean to say? I'm guessing "jumps"?
