If you don`t have a COP going bad then more than likely the TCC is slipping. I had a 95 Explorer that did the same thing. a simple trans fluid flush fixed it and it never came back!

BUD UM BUMP! LOL. good one.
Yes there will be 10 COP`s. when they go bad they can cause an intermittent misfire that will feel like a shudder. my Explorer would shudder when the torque converter started to lockup. once it was locked however it would be fine. it can be hard to differentiate between the 2 unless you know exactly what to feel for.

I bad boot or wet boot will do that and it feels like a u-joint gone out and only in overdrive. I would change all those if you haven't. Are you sure you don't have water in the plug hole(s) ?

Yes, it can only be felt at certain rpm's. Depending on which cyl it is it may be more or less noticeable at different rpm's.
