problem with my transmission on 2001 Honda Civic

my transmission went out I bough one from the used auto.. junk yard.. I drove it for 2 days before it put me down again.. now when I drive it , It will go for about 2 blocks and its like it gose in neutral, I cut it off put back in park and restart it put it in drive and it gose right in gear just like it should it go for another 2 blocks and start back over doing the same thing again.... I tried a computer I also tried a gear shift switch off the other transmission and still the same thing.. did I buy a bad transmission or something else.. also there is no flashing lights on the dash board and there,s nothing coming up on my meter.
