<VV> Transmission problem...

[Cash Case]

Hi guys,
I mentioned a few months ago that I had a strange transmission  
problem.  The gears whined in 2nd and 4th.  And it just got worse.  I  
had just 3 months earlier replaced the clutch and fly wheel (Solid fly  
wheel) and I wondered if the solid fly wheel was the problem. I  
finally got some serious under the car time and was going to pull the  
transmission and replace it.  I'm still going to do that, but I  
decided to see if I could pull the transmission without taking the  
motor out, so I disconnected everything from the front of the  
transmission.  The under side of the transmission was wet so I was  
concerned.  It appeared to be leaking from the shift rod that comes  
out of the front of the transmission. I remember asking if the backup  
light switch at the bottom of the transmission would leak fluid out if  
I pulled it out.  This one is damaged.  The answer I got was that it  
would indeed leak.  That made perfect sense.  After all it goes into  
the transmission case.  I pull it out expecting a flood of gear lube.  
It just trickled out very little fluid.

I think this is why the gears are whining.    2nd and 4th must be in  
a  position that they get starved of lube first when things get low.   
I've purchased a transmission rebuild kit from Clarks and I have a  
spare transmission that's going into the car for now.  I'll rebuild  
this one.

How can I tell if the gears are too worn or not to rebuild when I tear  
into this one?
