Can I upload this on fanfiction.net?

[Unclued]

You can post it, and you can get a lot of complaints about it. If it's not a derivative work (everything written in your own words, including dialogue) it will run afoul of copyright infringement. Quoting some dialogue is allowed. However you have to cite it in some way so that the reader does not think you wrote it yourself. And since you've stated you're straight up transcribing it then your work doesn't seem like it'd fall in the category of fanfic which is what that site is for. It's a very gray and messy area that you're probably best off leaving alone.
