So our 2014 diesel has been going into drive very hard lately. It would do it every once in a while over the past few years, but now it seems to slam every time you put it into drive. It also slams pretty hard when you let off the brake and the car goes back into drive from neutral. It doesn’t seem to do it when going into reverse. The car has 100k miles on it and had amsoil trans fluid put in around 60k miles. Is there something repairable that causes this? A solenoid or clutch pack or something? I’m fine with opening up the transmission to an extent, I would just like a bit of direction if anyone has any.
