engine or transmission stumble?

[Osiris3006]

Hey guys we have a 2014 SHO and have absolutely loved the car, however, we have recently been having an acceleration issue. The issue is more noticeable in D rather than S which makes me lean towards a solenoid in the transmission maybe? Upon acceleration we will on occasion get a jerking feeling like the car doesn't really know what its supposed to be doing. We are taking it into the shop in on the 5th of September, but since there are no codes I am hoping for some ideas to have them check out. We have approx. 41K on the car and have recently (<10K) swapped out the spark plugs. What do you guys think? Problem seems to go away once its in Sport...

Check for vacuum leaks?

Ill mention that, but wouldn't the problem always happen if that were the case?

I'm not sure. Things a all computer controlled.

Just my guess of things to look at.

How was the trans fluid level, looked/smelled normal? If the fluid is fine, I would try pulling the neg batt cable for 40+ minutes and then let the PCM relearn your driving style. Once that is done, see if the problem continues to occur. If so, since you have already done plugs, do a drain/fill on the transmission fluid. If it does help, it could indeed be a transmission related issue - whether fluid, sensors, or internals. One step at a time
