what are some sites that sell japanese "recycled" motor/tranny combos???

my accord's tranny has been slipping for some time & now that i sent the last payment this past weekend, i'm startiting to get some loss of power etc

car is still in excellent condition & i'm not looking to get rid of it anytime soon or buy a new one (no payment FTW), but after ~200,000 miles, it's time to do a little overhaulin if i'm gonna keep it for awhile

:sad:
