I'm making syncro noise on the 1-2 and 3-4 shifts on my <2,000 mile F35...

I see that Redline claims their 75w90NS will allow for smoother syncro operation, but will it shut them up?

I guess I'll have to live with the syncro chatter...this transmission is a joke.

I haven't beat on it, I've rev matched on 99% of downshifts (only slow downshifts haven't been matched), and I don't downshift this one very often...

I've treated nicely, and its still a spaz, maybe I have cable/linkage issues?

I also have the 3rd-4th gear whine (still do, last transmission did this too), which I was told was output shaft noise...I also told my shitty dealer this and they said all these cars make that noise. I don't have the option of taking it back on warranty, because they voided it, I just have the 12 month dealer service warranty...

 

RL 75w90NS has given me pretty good results in warm weather, cars that see the cold shouldnt really use it.

 

Thanks man, you don't think there's damage do you?

I just want to shut these things up...
