The drive gear should be basically directly under the driven gear housing hole in the tail housing.

If you have a plastic drive gear, there's a spring steel clip that has one end secured in a hole in the tailshaft. The other end snaps the drive gear into place. There's a chance the drive gear was knocked out of position, or the wrong size clip was used instead of the correct clip.

Steel gears used on some early transmissions are a press fit and I seriously doubt you'd be able to move one out of position under ordinary circumstances, so if there's a steel gear and it's loose enough to be bumped out of position you need to replace it altogether.
