I have a '85 300D. It seems to shift slowly (as in not having alot of pull,not really slipping) when its cold. After driving awhile it seems to run better. Also it doesn't seem to shift from 3rd to 4th as easily as it does in the other shifts (1-2, 2-3). It seems that I will have to be at about 40mph and at about 3200 rpm when it finally shifts to 4th. Sometimes it won't shift until I reach about 50-55 mph. The lower gears will shift right at around 2000 to 2500 rpm.
Do I have to go thru this same vacuum control curve adjustment?
