> *.encode('rot_13') ==> CodecLookupError

I like the idea of raising a lookup error on .encode/.decode if the codec is not a classic text codec (like ASCII or UTF-8).

> *.transform('ascii') ==> CodecLookupError

Same comment.

> str.transform('bz2') ==> CodecLookupError

A lookup error is surprising here. It may be a TypeError instead. The bz2 can be used with .transform, but not on str. So:

 - Lookup error if the codec cannot be used with encode/decode or transform/untransform
 - Type error if the value type is invalid

(CodecLookupError doesn't exist, you propose to define a new exception who inherits from LookupError?)
