i decided to look over the coupe and see what I could see since the PO said it had some trans issues. on first inspection all looked ok, then on a closer inspection of the vacuum lines i noticed the modulator vacuum line was in the place where the fresh air line from the cabin should be, on the intake side of the vcv, cool. i cant drive the car yet but everything else checks out ok. hopefully this was the trans issue. i can only get a first gear shift in the driveway so all i know now is it has a firm first to second shift with it floored.
