I posted a thread a while back about the vacuum modulator on my son's car going bad. I have replaced the modulator and the vacuum measurement is perfect. The tranny's fluid level is right up to snuff but it will not shift out of first.

For history, the car has over 260K on it and the trans was replaced with a rebuilt unit via Adsit. The shop that did it, an old Mercedes mechanic, always used Adsit. Anyway, the trans worked perfectly for maybe 5K miles and on a trip of 225 miles, at about 200, the tranny started having issues with shifting. It was driven the last 25 miles on 2 lane roads shifting difficulty from 1st to 2nd to 3rd and finally 1st to 2nd only. Towed the car home and went through tests and discovered the vacuum issue. Replaced the modulator valve but can not get it to shift. Bowman cable appears free and working. Does anyway one have suggestions as I am now totally clueless as to what is going on??

Thanks, Frank
