Hello i was directed to repost this in here as i mistakenly put it in the wrong section before. I own a 1987 560SEL my problem is as an example if i get onto the highway and go 1-60 it will shift very smooth. Then release the gas the breaks will apply themselves (which i assume is by design? quite annoying rlly tho). So it will drop to like 45-50 when i go to give it gas again it will jerk the car quite aggressive im assuming its the transmission shifting into a new gear? Im just not sure if this is considered normal or if im breaking something by driving it around.
