<VV> PG no reverse and more

[Steven]

Yesterday I drove home my 3rd Corvair.  340 miles.  Before taking the car I 
test drove it and it shifted fine, all gears seemed OK.  Fluid level was OK. 
Previous owner said it has had a small leak for 10 years and all he added 
about 1 pint at the beginning of each summer.  So anyway, after about 100 
miles I take a rest stop and in the parking lot on a hard right low speed, 
the PG slips.  While filling the gas I checked the fluid level and it was 
about 1/2 pint low so I added a few ounces of tranny fluid.  All good on the 
highway.  Once near home in the neighborhood again I have slippage on a hard 
right.  This all not so bad?  But this morning, I start her up and I have no 
forward and no reverse.  I check the ATF and the dip stick has nothing on 
it!!  There is no fluid under the car on the ground.  I added about 1 pint 
and I seem to have forward, but still no reverse, and I have to back it up 
to move it.  So, does this make any sense?  Can the tranny be that low on 
fluid and still have seemed OK?  I'm thinking of just adding ATF unitl I see 
the level on the dipstick.  Is this safe or do I risk overfilling?

      Thanks
