I remember reading a quote that unmistakably demonstrated that +Lefebvre believed one can be saved outside Holy Mother Church.  Perhaps he was just parroting the error/s of his age, but reality is reality, no?

Frankly, it would be more beneficial for everyone if +Vigano asked for prayers for +Lefebvre's soul, rather than acting like it is a given he is already in Heaven.

• Page 216: “Evidently, certain distinctions must be made. Souls can be saved in a religion other than the Catholic religion (Protestantism, Islam, Buddhism, etc.), but not by this religion.  There may be souls who, not knowing Our Lord, have by the grace of the good Lord, good interior dispositions, who submit to God...But some of these persons make an act of love which implicitly is equivalent to baptism of desire.  It is uniquely by this means that they are able to be saved.”[1]
  
• Page 217: “One cannot say, then, that no one is saved in these religions…”[2]
• Pages 217-218: “This is then what Pius IX said and what he condemned. It is necessary to understand the formulation that was so often employed by the Fathers of the Church:  ‘Outside the Church there is no salvation.’  When we say that, it is incorrectly believed that we think that all the Protestants, all the Moslems, all the Buddhists, all those who do not publicly belong to the Catholic Church go to hell.  Now, I repeat, it is possible for someone to be saved in these religions, but they are saved by the Church, and so the formulation is true: Extra Ecclesiam Nulla Salus.  This must be preached.”[3]

From his book against the heresiesI heard from a priest that Padre Pio had to spend the time to make 1 genuflectiom in purgatory. Going straight into heaven isn't easy, AB Vigano's statement is a bit rash.
