You can find some transcripts of varying quality and completeness on these webpages:

Livedash.ark.com and allreadable.com also have transcripts, but you'd have to look harder. Netflix and the DVDs, if you have them, include the best quality closed captions in at least English language, but you'd have to transcribe them manually if you don't have a way to extract the text (I'll leave that to the programmers here).
