'94 C220 with 45,800 mi, all services performed, new wiring harness and a lot of litle things that make this a really good driver, but one thing doesn't seem right. When cold the upshifts are really jerky. As the car warms up the shifts get pretty good. Not as smooth as a newer model, but pretty close. This has been going on for a long time. I had a '96 E320 that acted the same over the last year or so. Seems like it may have started after the 30,000 mi fluid change. Thoughts?
