Unexplainable Transmission Stutter... help?

TrailBeast said

A vacuum leak would/could cause the plugs to look the way they do AND cause what sounds like the miss.
It is obviously richer'n hell, but some plugs show pretty lean.
This can happen when air is getting in somewhere it shouldn't. (vac leak)
You sure you plugged everything back in (even on the back of the carb?)
Vacuum leaks can be anywhere, not just the vac can hose.

Did anything go on in the trans recently?
Filter change or anything?

Also, are you holding those plugs in the order they go in the motor?

Looked a little rich, but the car also hasn't been driven and those plugs are 1step hotter than the champion plugs even with them being the cross reference plug. I got some autolite 65s just now and it runs the same lol.

Yes the plugs were held in order that they came out. Its habit to take them keeping them in order and putting them back in the same hole they came out of.

See pics/ videos below.

Carb plugged in the rear (always was). Distributor to carb vac line reinstalled. Vac line at expansion valve (? I think that's what it's called for the ac/heater), vac line for on the intake is hooked up.
