RIP 5th gear synchro, you served me well.
 

So after at least 4500+ track miles and a total of 68k miles my 5th gear synchro finally gave out. Was a NJMP Thunderbolt yesterday for a track weekend when at the end of the 3rd or 4 session I could no longer get 5th or 6th gear. I was debating to keep going today since I only use 5th for a bout 10sec on the straightaway but I didn't was to stress the car more and go for the rest of the weekend when I could still get credit for a future event.

Anyway, now I am on the hunt for a '16+ transmission, I think those are made better then the earlier ones? What's the going rate for a used one with about the same milage or less, eBay seems to show around 1.6k. but alot of dealer websites show around 1.9k new?

there are several used ones on ebay in 600 to 1200 range

Maybe I'm searching something wrong? I can't find ones less then 1.1k and their '09 or almost 100k miles.

I may be in the same boat looking for a transmission after a recent track day...…. good to know that the '16+ are built little better.

"boy...…...you f*cked her real good their buddah!"

after a few track days myself I too have 5th gear grind....gotta look for a new transmission lol

Just get a new one. It is not worth taking a chance on a used one with who knows what is wrong with it.

Do you know why the 16+ is better?

Same 5th and 6th are gone for me too. I wish there was solution

No real evidence, just 'I heard'. Also, the new transmission is just as annoying to get into 5th as the old one when it was new. So I doubt now there is any difference.
