Does anybody know if the vacuum line to the transmission on a 1982
300TDT is ganged with the automatic locking branch of the vacuum
system? I capped the line that goes to the locking system at the
junction connection in front of the firewall.
My tranny has been shifting down hard into the bottom gear and someone
said that was because the vacuum control was not functioning and now I
think I may have disconnected that line too when I blocked the vacuum
locks. Where I live I seldom have to lock the car, but I don't like
the hard shift down which will eventually start to damage the drive
line components. I may have to route a line especially for that
control unit on the side of the tranny.
I have tried to fix the locks, but I can't seem to locate the leak. I
think it must be in a line because the actuators in the doors,
including the tail gate, all have been replaced and seem to be fine.
