So I have a 2012 Hyundai genesis coupe 2.0T automatic, i purchased it at 53k miles from my job the car ran great.
I noticed at around 56k it had an oil leak from the line that connect the oil filter and the turbo , I changed that piece and changed the oil to w5-40 and the filter.
Now I I'm not sure if it was happening before and I never noticed but when I I accelerate from 1st gear my car jumps to 3rpm shifts into 3rd then shifts into second then after awhile of going maybe 40 goes back into third.
I asked a coworker who works with cars and he said it could be a shift solenoid I'm just going it's not the transmission. Maybe im paranoid though and it's normal? Any help would be great
