Hopefully, I'll have more luck getting some info with this thread.
In short, I've a '99 with the 2.5L I4 and an AX-5 tranny. Yes, I know they're not the most robust beasts in the world.
Recently, when I'm downshifting into 2nd at anything over 1k RPM, there's a noticeably loud grinding sound before it pops in, which requires more force than it used to. Going UP through the gears presents no problem, and once I let the RPMs drop below about 1k, it's better.
Are my synchros heading south? Any kind of additives I should be looking at?
Thanks, I hope, for your help.
