Not all rebuilt transmissions are created equal. Especially after 6 months of service and a trip through a salvage yard.
From the sound of things, you have another failed transmission on your hands. This may have been caused by debris in the cooler lines. Is important to flush out the cooler lines when replacing a failed transmission. Material given off by failing components can lodge in the trans cooler, and return to a replacement transmission and cause the replacement to fail. Worse yey, if the cooler is blocked or restricted, a replacement transmission will have a short life.
I have rebuilt many of these units, and have had great success, including my own. Mine now has been working perfectly for 5 years since rebuild.
Unfortunately, some rebuilders will overlook some of the really important finer points of the transmission. One of the things that causes early failure is rear unit end play. The direct clutch runs on two delicate rubber seals. Excessive end play will destroy these seals in short order because the direct clutch drum will not run true, and can wobble. Clutch pack clearances are also important. Too loose, and they will jerk on engagement. Too tight, and they will drag and cause early failure.
My best suggestion is to make sure that the cooler is clear, the converter is clean, and start again with a rebuilt unit.
