'03 Touring: 3rd gear gone - options?

'03 Touring: 3rd gear gone - options?
I know common problem, synchros in 3rd are going, going GONE at first it was random grinding, which became lots of grinding when driving hard, to now almost constant grinding even when going S L O W clearly she is a toast!
So what to do?
Tranny rebuild? The problem will just return at some point right? So that doesn't seem very logical. Can synchros even be "fixed"?
Put in the infamous CD009 tranny? Seems like a good idea... so what do I need?
Smaller pivot ball and??? Something about a fork? Sorry I'm not knowledgeable in this at all
Do ANY and ALL CD009 fit into 2003 Zs?
Anything else to look out for? Is this a simple swap? IE: direct bolt in - thus any grease monkey with tools could handle it? I can't seem to find any DYI guide or write-up despite lots of people here claiming they done it.
Sorry for so many questions but most of the topics I find here end with someone saying they did the swap but without posting any details or a checklist of part or steps. Maybe this is super easy and I'm over thinking it?

Tranny rebuild will cost more than a used CD009 transmission. There is a DIY out there somewhere I think. My '03 has the CD009 which was replaced twice under warranty, at least you only have to worry about 5th/6th gears grinding with this version
I suggest you start searching through ebay/forums/facebook for someone selling a used transmission.

Yikes - what happened the other two times? 5th let go?
I've started digging around on eBay, I'm just unsure if a buddy of mine who does engine work can handle the swap. He is a whiz at old school (muscle car) motors but has never done any transmission stuff. Like everyone else I'm trying to figure ways to keep costs down. A used tranny along with DYI makes this problem go from a disaster to just an annoying problem since the cost is half.

First replacement transmission - 5th gear synchro began to grind.
Second, and current replacement transmission - 5th & 6th gear synchro's now grind. It's just something you have to live with on this platform, baby shifting into 5th/6th because Nissan is cheap. Or spend $10k for an aftermarket transmission...

So back to my basic question: can you DYI this tranny swap of CD009 into an '03 or should I take it to a shop? I'm trying avoid dropping $2K on something that is clearly going to break again

You can do it, lots of other people have who weren't as lucky to be under warranty like I was:

I love how that one thread says "Definite answers for 03 CD009 swap" then proceeds to list three questional items: clutch fork, shift bracket and frame sensor. You can see where the confusion comes from. Thus my confidence is not high.

Haha, yes the information is definitely scattered about a bit on this one, but I'm certain once you have the transmission dropped, and are hands on it will become apparent. If you have access to a lift it shouldn't TOO terrible, just get yourself a Hayne's manual, and get to work. I'm sure it's worth saving the shop labor... then again sometimes I can find mechanics that will do things for dirt cheap, and I suddenly become lazy.

Just did that... unfortunately it's 90% about the G35 Sedan with minimal 350Z info. It covers the basics, so I'm going to give to my friend to get his option on doing the work at his place. As I said before he is an engine guy and usually does not mess with transmissions. Also going to get a quote from a local place on prices if I supply the parts. Shipping alone is $200 new or used unless I can find one locally. Got a feeling if I'm about to become $2,000 lighter in the wallet

Your best option is a factory remanufactured transmission with an OEM warranty. That solution is slightly more expensive, but it is infinitely better from a practical standpoint. This way you have a reliable warranty that you can depend upon if there are any additional problems.
You are looking at $2500 for a good fix.

I'm still exploring options, mostly getting a used '05 tranny since that's when the CD009 became factory installed. I can tell you the best thing so far has the been the Service Manuals found here: http://www.nicoclub.com/FSM/350Z/. Based on further research it appears if I get a complete transmission then I have everything: the tranny itself, pivot ball, throw out bearing and the clutch fork.
Thus it appears to be a direct swap with only a few parts getting in the way, namely: the cross bar support, catalytic converter (PITA?), drive shaft (duh), control rod (from the shifter assembly) and various sensors. Also it seems the start motor gets in the way. Any comments on this list?
Once again I'm trying to prepare the person who is helping me with pain level required to pull this off. Is this a 6 pack or a 12 pack job? or does it make sense to pay a professional given my utter lack of knowledge on the subject

So now I have to decided new or used tranny...
New is nearly $1,900 with shipping
Used is $700 with local pickup
So I can save $1,200 but risk going down this path again in unknown miles / months Seems worth the gamble to me.
