Friend owns a 19?? 300SD. Runs fine although I always noticed the 1-2 shift was rather abrupt but not enough to jerk the car, and the 2-3 upshift happened amost right after the 1-2 shift. Now the car does not shift into 3 or OD. Friend claims the transmission is filled up with the proper type of fluid and does not seem to be a linkage issue. I know that Ford transmissions use a vacuum modulator that if disconnected can cause hard shifts. Any ideas to try before the transmission gets rebuilt?
