You will want to be very careful in buying a used tranny unless you are satisfied you truly know its condition. That sounds obvious but there has been some sad stories.
If there are some unknowns that concern you, might be worth comparing prices with Rodney at RPM Transmissions, a well respected forum vendor.

I think that the material used on the blocker/syncro rings is different between 01 and 02 I've heard that some synthetic oils will eat the early rings. might be worth checking out before purchase.

I have never heard that, but would be interested to know if that has any truth because I was planning on changing mine to synthetic. Anyone with '01s experienced this? I thought they were all the same. Just the shift fork change in early '03.

I can't remember where I read that info, as I remember, it was what I felt to be a reputable source, and it concerned early C5's only. I Don't remember the year split. There was A list of synthetics that were acceptable, All I Remember was 03 Trans was OK & Mobile 1 was one of The oils that was not acceptable on the early ones. I Usually print stuff like that, Ill see if I can dig it up for you.

Nope, I didn't print it out, probably because it didn't pertain to my situation. Today when I go to work I'll check it out, and see if I can determine exactly when the blocker ring change occurred.

Try them--for $1k you get a good rebuild if yours is not trashed.

Checked on the syncro rings today, It was not as easy as I thought to find the info I was looking for, due to the rings retrofit back, so all the parts books show only the carbon fiber ring. I had to dig in the old parts books, It appears that that the change occurred in 1999 whether it was a Domestic or an European version, after that all appear to use the new carbon fiber rings which synthetic oils will not damage. One thing to take into consideration before a switch to synthetic is the oil does help prevent seizure, your blocker rings are (brakes) they work off friction, if you change to a synthetic and you pick up some gear clash (Grind on shifts) after the change, change back, you will cause $$$ worth of damage over time. The transmission was designed to run Dextron ATF. I'm absolutely not against synthetics, but even in our most severe duty automatics we run a mix of 2/3 mobile 1 & 1/3 high grade Dextron. We have found on occasion, sprages (type of one way clutch) will slip, that look just fine, and just a switch back to good old dextron takes care of the problem
