just bought another one (the 300TD) that shifts perfect
. I am considering connecting the vacuum gauge (on the 300TD) to the line going to the tranny on it and see what kind of numbers I get. The 300D is still in high gear by the time it gets to around 30-40 mph. I've replaced the Bowden cable, checked the vacuum modulator on the side of the tranny and replaced the round "blue" vacuum controller located on the drivers side engine compartment and it still shift early. When I get the 300TD like I want it I will get back on this. Sometimes I wonder if it is actually in the transmission itself.
