Anyone ever "fix" a scratchy synchro with fluids?
#25
what does it do specifically? Grind? Tough to push it into the gate?
Mine is an absolute clunk box when its cold. I have to seriously put effort into shifting smoothly, but when I do, its totally fine. I'd keep revs from dropping too fast between shifts and that seems to avoid any notchi-ness or roughness. It doesn't grind though, just tough and rough switching between gears.
When its up to temp it shifts like butter. Flawless.
Is yours the same way or always clunky?

Once a synchro is worn enough that it no longer has the ability to act as a brake and slow the gear, there's no reviving it with fluid. You can potentially change the way the trans feels/shifts with a different viscosity gear oil, but if the synchro is worn out and grinding, it's done. There is literally material worn away from the inner contact area, or the teeth are deformed enough, that it can't function properly any more.
And make sure your clutch is properly adjusted. I'll assume you know how to do that and that your clutch is not dragging. Which is the #1 killer of synchros.

Are you serious? Why the sarcasm? You are asking if a fluid could fix your trans... All I was doing was making a suggestion. Lighten up. I didn't say it in a condescending way. Why ask questions and then **** on the answers? We ALL know if the trans is acting as you describe the only real fix is to replace the failed parts. Maybe next time just don't reply to posts that you think are stupid? Sorry if I am coming off as a dick, I just don't understand why people ask questions then get pissed off when they don't get the type of answers they want. Feel free to weed out / delete my posts if you find them unrelated or not helpful in any way.

The vast majority of "bad syncros" are actually the result of a bent shift fork. Its pretty unusual for a syncro in a good, modern transmission to just get shitty out of nowhere. Typically a shift fork gets bent, it starts grinding, then after a year of that ****, the syncro is torn up so when someone opens the transmission they go "oh, look at dat der syncro dats all tore up, ders yer problem".
So no, I dont think any kind of fluid is going to help. Going to a different weight might make it shift better so you dont bend the fork in the first place, but thats about it.
In the mean time, double clutch...
