The electron does not transform into a neutrino.

e^- -> ν_e + W^-

is in error. It should read:

e^- + ν_e + ν_e -> W^- + ν_e

or Right Side = ud + ν_e

I don't know where you got the first equation, but electrons don't decay. Even if they did, they couldn't turn into a W- boson, as those are much more massive than electrons. The only way I could see an electron giving rise to a W- boson (other than virtual W- bosons, that is) is in a high energy collision.

Is "Electron Transforms Into Neutrino" Erroneous?
Yes, they seem to be another of the OP's errors.
