The pump to which I refer is the electric pump pressurizing the hydraulics of the braking and clutch systems as from "M89 on. . . " to quote from the factory service manual. This is on an '88 9kt, the year the 9k's went to ABS, and when they did, the pressure for the hydraulics is via electric pump, and not vacuum assisted servo. But your point is well taken. I was vac bleeding, and I did think I could get additional air from the threads. What do you use to pressure bleed? Hopefully it's not some $175.00, Saab proprietary, modified tire pump, that I'll use once every five years, if that. Somehow though, once the air is removed, I still think I am going to have a problem. Once the car ran for a while, without much shifting (e.g. highway driving), it would sometimes come back up. What else could affect this? I don't think it is the clutch itself, though there is ~115k miles on this one, but once engaged, the clutch, does not slip.
