Hello

so my car suddenly showed "check engine light"

and when i used the scanner i got code P075x

i dont remember what it was but it was about solenoid A

i turned it off and it didnt pop up again so far

however yest the car kinda had a weird shift between 1 and 2 but that only

happened like twice and other than that car runs and shifts great

my question here is this a bad tranny or just change the solenoiod and oil and all will be good ?
