95 Maxima SE Gearbox

OK, what makes you say that?

Well, you could try applying the clutch and selecting each gear to see if anything happens. Does the clutch 'feel' right? Is the gearbox making any noise? Have you pulled the plug on the gearbox and looked for 'parts'?

Only the gears? I wonder what something more drastic could be in a gear box ;)

Give a bit more info if you can. What have you tried, symptoms etc.

The car now does not start bec. I am in process of doing the altenator.

The car goes in ALL gears while car is off.

When car on, no luck w/ the gears.

BTW, yes replacing gears in gearbox would be the inexpensive compared to some parts in there.

Bad clutch slave or master cylinder likely.

If it is grinding trying to go into gear, it is probably a clutch, linkage or cylinder/s issue.
