Apparently the 6-speeds need a lot of specialized tools to properly service them, unlike the 5-speeds. I also talked to Shep Trans today. Turns out, they only do EVOs and GTRs, but the guy was nice enough to give me some pointers. 1. $1000 is pretty standard for tear down, inspect, reassemble. 2. So with synchros and maybe a couple other things, it quickly becomes $1300-1500. 3. Generally if you are having issues that require synchro replacement, there is also other damage and that quickly puts you well over $2000.
From what I generally see online, a lightly used 6-speed goes for $3,500-$4250. Of course that includes all the axles, driveshaft, hubs, etc....which I don't need. If I could just buy a brand new transmission by itself for $2,000 then that might be something to seriously consider. But I don't see that option available anywhere.
Maybe that's something [MENTION=6480]kenziel1203[/MENTION] would know.
