All the gospels have a different slant on the message for the purpose/role each was to play in the finished cannon, but pretty much consistently without any contradiction.
I would contend that the reasons the Gospels changed were mostly sociopolitical.
In addition, John paints Christ as a much more symbolic "sacrificial lamb" who's sacrifice had to do with an eternal, spiritual salvation.
That's why the timing of the crucifiction is changed in John.
The other three gospels are talking about Jesus coming back very soon as a military leader to conquer all of Israel's enemies, but by the time John was written, it was pretty clear that this was not going to happen. That's the reframing, or
tweaking of making Jesus' sacrifice a symbolic one for all of the future.
