rebuilt Getrag problems

I got a rebuilt Getrag off ebay and it worked without issues untill the 310 mile mark. Down shifting from 4th to 3rd it started catching a tooth going into 3rd. within the next 100 miles it won't go in 3rd without serious grinding. Going up in gears is no problem, smooth ingagement. I've stumbled onto the only way to down shift into 3rd by attempting to go into 2nd, (witch is impossable unless your 10 mph or less) then attempt the 3rd gear. It goes in 80% of the time without catching a tooth. I had the dealership swap the trannys and they filled it with the proper oil. So the first thing I did was to change the oil with 5/30 Mobile One (3 1/2 qts and penzoile snycromesh 1qt) for a grand total of 4 1/2 qts. Still no change and the oil I removed was dark gray with pretty gold streaks flowing around. Also if I hold the shifter up into 5th gear all the way against the gate I can feel a tight bearing vibration. Using the 2nd gear attempt seems to slow something down in the tranny to allow a down shift into 3rd from 4th. I down shift into 3rd at 35 to 31mph, that should not be too fast.
Any thoughts would be welcome. Dave
