im guessin its the starter. the solonoid on the starter has been known to work intermittently. its not uncommon for a starter to fail when installed in the tranny, but seem to work fine when bench testing.
be sure to check all you connections to the batt, ground, and starter. be sure you got a batt with a strong charge, that will be sure to eliminate that as the culprit. if your battery and connections are good, and your starter is making a clicking sound, i got my money on the starter.
for sh!ts and giggles, try giving the starter (solonoid) a few medium raps with a hammer, wrench, dowel, or something. dont hit it so hard as to break something, the soloniod housing can distort really easy causing the gear mechanism to bind.
now if your starter works after a few medium hits, change it out.
