I have a 2010 mercedes e350 with 70k miles and it’s starting to shift really rough. I did have the sealed transmission fluid changed for 400 bucks at 50k miles, would that have caused this? Sometimes the abs light flashes along with the srs and a/t temp light. I was thinking about selling this car but I saw online that they don’t go for much, any ideas on if i should fix the problems?
Thanks for the help!
