Swapped a 1998 Honda accord 4cyl transmission for a 2001 accord transmission and it does not shift right?

the trans is probably not anny good. i went through 6 of them in my 98 accord before i got a good one. they have major problems from 98 to 01 the best thing to do is get one directly from Honda they offer them really cheap around 1500.00 due to the problem and they come with a 2 year 100000 mile warranty. normally that would be a 2500 trans.
