So recently I have felt issues in my car but nothing was actually an issue.
It may be the oil since I topped it off myself a couple days ago. I put in havoline 10w40 because the gas stations around me didn't have mobil 5w40.
I feel like I have the worst tranny in the world. I noticed this around the early 100 miles on my car, but I think I may have broken in my car wrong by pushing it at 700 miles but I doubt thats the actual problem. I absolutely cannot stop at a stop sign on Manual without the car feeling like its a HARD stop and start. For a fact I know that it shouldn't be doing this 90% of the time, and I hear you don't have to shift to first gear on Manual but also if I do with even 2k rpm or less I get a lot of jerking.
Also today I was driving in manual right about to be at my gate (231F temp), and when I switched the gears from Manual to Comfort, the car completely freezes, the wheel locks and all of the lights are on. I slid it to park and then turned the car off. I waited a minute and turned it back on and heard kind of a harsh quick sound and i was checking if my car was able to drive by going around the block a couple times. It seems completely fine now, but the question is why, and should I be worried?
I haven't gone to the dealership because I have to wait the next day just to get my car looked at and being my only car, I can't do that.

This is why they have warranty, just take it to the dealer and tell them to fix it.

Just take it in. You need to know what's going on and they'll fix it. If you can't be without a vehicle, they should give you a loaner.

All the lights coming on switching modes was the red flag. Don't worry about how you broke it in, that has been debated for a long time on many different platforms. Not the issue. Also, it is a slow shifting rough tranny, an ecu/tcu tune smooths that out and the oil has nothing to do with it. But, when you take it to the dealer maybe get a change anyway and always put the same kind of oil in it.
