1983 Mercedes Benz 240d 4 cyl Two Wheel Drive Automatic 250k miles
My 83 240Diesel is in terrific shape. Engine runs great. I am having trouble with the shifting points on the transmission. From a stop, car shifts almost immediately @ 5mprinto second gear. Next shift is @ approximately 20mpr and next shift @ around 35mpr. If I manually downshipt at this point the trans will kickdown into lower gear and really has grteat acceleration (for a 240D). Also, once trans has shifted through the gears, I feel as if the highest gear is not engaged. I may be mistaken but at 60mpr the car is really performing well but when I take my foot off accelerator, it feels as if the car is slowing down quickly as if the gears were doing the work. Can it be that it is not shifting into 4th?
Should I change the Vacuum contol valve and the vacuum modulator valve or wold some adjustments work? Thanks.
