Ben was my advisor as well(quite a charmer...NOT!). the part number you have for the trans cable is the same one they are calling "upshift valve" 124-270-16-73. Part cost is quoted at $170. The other part #'s are:
000-141-57-25-81 "Throttle Valve"
124-545-65-32 "Control Unit"
They replaced my fuel regulator and the starting issue is gone. $67 for part 127.50 labor. The car runs great smooth as a cat. All this emissions stuff is the major problem
