yes it was slipping before, i changed the fluid and filter, took it for a test drive and it worked fine.. took it back in the garage to change the tires went to pull it out of the garage and the car wouldn't go into gear. took the transmission out and the pistons exploded inside, soo thats when i rebuilt it. and my scanner didnt pick up any codes

Did you ever perform a transmission pressure test?Thats the first thing you should always do before a transmission repair.
