Auto to Manual

Ok, I have a 03 tl type-S that I have not had the first sign of a problem from the trans, but the 100,000 mile warranty deal is coming up in the next year or so and I have been wanting to pull the auto trans out and replace it with a manual. The question I have is what trans is offered for that car that is reliable and compatible? The second part of this question is, if a trans is avalible, where do I find all the nick nack parts to make this work?

Don't do it, it would be a million times easier to just get another TL with a manual.
