No, not even close. We just took the old testament. We didn't change anything in it.
Quite correct, there is no "replacement." All of the Torah and OT are still intact and unchanged. Christ even confirms this.

The concept of the Trinity itself is a massive modification of the Old Testament. Also you'll find that if you compare a Hebrew bible to a Christian text, there are differences throughout. I'll often get into a theological discussion and find my text has different line numbers and translations than a Christian text - also I have a comparative Bible that shows even among Christian texts there can be significant differences.

You're both wrong. Christianity changes a lot of the Old Testament. Large parts of God's laws as set out in Leviticus are denied by Christians entirely.
