Aperture Linkage - Vivitar MC 2x teleconverter

i've just picked up a Vivitar 2x teleconverter on ebay. I had my A 50mm on with Vivitar extension tubes - aperture linkage working fine. Swapped the teleconverter in for the extension tubes - problem... no aperture linkage. I don't mind doing things manually, but I was just intrigued as the teleconverter has the little aperature hook on one side and the piece on the other and they seem to move about okay. Is it an older mount or is mine broken? Or more likely... have i missed something? thanks!

I have a vivitar 2X-22 teleconverter and it supports automatic apature.

You should mount your lens on the TC first.

check that the apature indication moves when you turn the apature ring, this is almost flush with the lens mount,

then chefck that the apature activation lever opens the lens up, when it is stopped down

As far as i can see both of the levers are moving fine. But I can have the lens on my camera working correctly, take it off, put the tele converter on the lens and everything seems to move fine when i turn the aperture ring and i can move the blades manually as i'd expect, but then i put it on the camera and it don't have linkage :s
