Just got my Nikon TC-14E II and it's not working with my D800.
With Nikon lenses the aperture blades close until you mount it on a camera and turn it on. Once you do that it will open the aperture to it's widest settings, that part is common amongst brands. When using my TC-14E on the D800 the blades never open on the lens. Same results with my 70-200 and 300mm lenses. With my D5100 it works just like it's suppose to, not a single issue.
I went ahead and reset my D800 to default settings and cleaned the contacts in the body but the issue remains. My D800 works perfectly without the TC-14E and I don't have the same problem with the TC-20E.
Okay my TC situation is getting stranger. I did play with the sequencing when the TC and then the lens goes on and it didn't make a difference.
What I did was shine a light through the VF so I can actually see the blades better when putting the lens on. What happens is the aperture blades are opening during the mounting process. As you twist you can see the blades open. When I mount the lens once in a while I can see the aperture blades opening up. Give the lens a little shake and the aperture blades close up! This behavior happened regardless if I had the TC already on the lens and was mounting it to the body or if the TC was mounted on the body and I was mounting the lens to the TC. Exact same thing! Once in a while the blades would catch and then just close up.
I do the same test, shaking and all, on the D5100 and nothing! It works perfectly! It sounds like a mechanical issue but it doesn't happen when mounting on the D5100. This is strange!

Even though you cleaned the contacts it sounds like an electrical problem to me which would point back to those.
I think I will just give up and return the TC. My D800 works with all my lenses and I can give the contacts another cleaning but trying another TC I think is the next troubleshooting step.
Good move, it's not your problem to trouble shoot a new lens. since everything else is working fine it's more then likely the TC. I bought a new 1.4 when I got the 800 and it's been perfect with both the 800 and now 800E.
