I will freely admit I beat the snot out of it. The 3rd gear synchro problem is a fairly common problem with this trans though.
When I bought the car with about 100k miles on it i would only get a slight "nik" going into third when shifting fast at 6k+ rpms. Now it is happening at more typical situations when hustling into traffic and is now a solid crunch. I'm know how to avoid it, but as shifting a manual trans becomes a "muscle memory" affair, it is easy to forget to slow the shift down.
So nobody thinks my "new fluid will be too slippery" theory holds any water? My rudimentary understanding of synchros is that there is some kind of clutch material that grabs to get the gears to match speed. I am wondering if new fluid would just make these clutch surfaces slip more.
