Hi,
I have a 1983 300D with the 4sp auto. I replaced the vac. valves on the valve cover, as they were worn through. It shifted fine before the replacement, but after that, I have a very hard 1-2 shift, slower 2-3 then a very long 3-4 shift. With each longer shift, there is no flare of the rpm, etc., but it takes a while in between gears, which bothers me, and Id prefer for the shift to be harder, so that parts arent wearing as fast. I assume Id need to adjust the bowden cable and perhaps the vacuum modulator, but any advice on which to do and in what direction?
Thanks,
JMH
