auto stick shift slams hard into all gears. vacuum lines are tight.  Control valve adjustments have no effect. What is the problem?  Are control valve parts available or rebuilt?

Sounds like you got it. The diaphram in the control valve must be
defective for it to not make a difference. If you shop around on the net you might find one. try the Samba.

If you have a hard time finding parts try asking around at Auto Stick Register...

Hi
Has this always happened?
the control valve is governed by the small vacuum hose that goes into the rear of the carburetor
[rear of the car] it MUST be the correct vacuum pipe/port
on the carburetor otherwise there is too much vacuum which causes the control valve to release the clutch VERY FAST causing the slamming You are experiencing.
