Have 1984 300D with 310K on it....very good condition, strong runner. Developed
a transmission problem in the past few days...shifts normally until the last
shift up, and then stays there until RPM gets up to about 4500-5000, then it
shifts into drive.
For a few days, this was the only problem...it would act normally cruising
until I slowed all the way or stopped.
Today it has the same symptoms, EXCEPT if I am running at 80 mph (for example)
at about 3500 RPM, and then slow down to 60'ish and the RPM drops below about
3000, it kicks down a gear and the RPM jumps up to 4500 until I speed up again
and puch the RPM to the high 4500-5000 shift point.
Any advice? Anal maintenance at dealer, but transmission has never been
