'87 300d transmission downshifts

My 1987 300d is a great car, except that recently it has been downshifting way to much after I drive it for a long time.


After a couple hours of driving it goes into first or second gear, and does not want to upshift.


What can I do about this?

Your transmission is aging, and needs a filter change. Look for friction material in the pan and on top of the filter when you change it.

Update:

I replaced the transmission filter and the transmission instantly started behaving properly.

I have been driving it for 6 months and it has been working great.
