I think is the problem with ur synchros,it happen to my 1,i try redline oil dosnt work,then i have to change the synchros and gear!

Your lucky if its "just" the syncro, if any other parts are damaged it will cost alot more, best to get a full gearbox reuild.
I don't know about the s2000's but my old car 2nd gear syncro and 2nd gear was the most expensive outta all of them.

there about $60-$100 more expensive then 3-4!

i get crunches and grinding when im cruising, but when im punching it, its fine.
the labours will be a bit on changing the syncros aswell.

When during the high rev,at the top end 90% is the syncro problem,if you gonna open up,make sure check 3.4.5....

Its a common problem with the earlier AP1s to crunch 2nd. Not much can be done, check the TSB on S2ki.com. This issue is on the list pretty much next to clutch buzz and plastic window cracking.

like this guy said check out S2ki.com

everyone else please stop saying its a synchro problem,we know nothing about the car,not even how many km's on it,what oil in the box,when oil was changed.
sure it may well be synchros but thats the easy answer out,could just as much be poor shifting,dodgy oil or a common problem with AP1s.

I would definitely atleast try changing the oil before i got all gung ho and ripped the box out to change synchros.
