I cannot find any info here on the adjustment tool. I have the '85 300CDT with the green bodied modualtor valve with the black cap. I have been through the searched posts and even Steve B's MB transmission info at Continental Imports (http://www.continentalimports.com/ser_ic20242.html) ref. figure 5 and it does not mention if this is a special "MB tool". I want to give the adjustments a try but if I do not have the correct tool for the mod valve I do not want to start yet. Any enlightenment appreciated.
