[whatnot]

My transmission is getting really noisy and I need to do something soon. (bad bearings)

What is the best way to go? Get it repaired, swap in a used trans or get a rebuilt? If used, what years will fit and what mileage range should I stay under? What else would I want to look at?
I had decided to send it to one place I found that said they would repair it for under $2k but then I did a google search on them and decided against them from what I found.
Now not sure what to do. I am just afraid if I put in a used one, it will have a bad bearing in it.
