My 2002 Nissan Xterra will not go in reverse and will not move in neutral at all

What is your question?

I still have drive but not able to drive it around the block because I can’t back out of the driveway I was told it could be the torque converter but cannot back up.

What makes this problem better or worse?

Will go in drive and will not move in neutral so I can push it.

How long has your 2002 Nissan Xterra had this problem?

Last week and haven’t drove it since.
