4L30E rebuild or replace

Long time reader, first time poster!
I have a 1998 Honda Passport 3.2 automatic, that I have owned for roughly 7 years. I replaced the motor in it after a few years the the transmission started acting up and replaced fluid it help, drove a little while longer, and the Transmission basically went out, it’s slipping and slam shifts. I parked and it has set for the last 3 years. I pulled it out, got the motors running good, and now it’s time to address the age old issue the 4l30e…. So all that to ask…. Rebuild or junkyard? How much are you guys paying to have them rebuilt? I know there is a wonderful thread on a guy that did it himself and I just don’t think I’m that good! If I get one from junkyard I know all I am doing is pushing this issue out for a later date. Any suggestions? In east Tn, any rebuild shops close that’s have had success with ? Thank you in advance.
