Toughness of our tranny...

Came back today and felt really good, plus the weather was beautiful, so I drove briskly around the backroads. Was much fun till I accidentally missed my upshift to 2nd I think I probably ground it a decent amount. So now I'm paranoid because this is the first time I've ground any gear. I roll up the windows and listen to the sounds of the tranny meticulously. Now I can hear the synchros and I notice a whine when I engine brake (sounds kind of like an airplane). Maybe it's because I'm very paranoid and now notice these sounds, but I would be much more assured if anyone can confirm this is normal and that I have nothing to worry about. :o

Thanks,
FS

don't worry about it, the noise is just clutch chatter, I have the same with my rx8 and it only has 500 miles. It takes alot more than a grind to ruin the synchros.

My tranny makes all kinds of funky noises, I think all make a lot of noise it's just that our engines are so quiet you notice it more.

I also noticed that whine when I engine brake after accidentally spinning my tires for the first time and I thought I messed something up...Turns out it's normal and we've just got a noisy transmission. Don't worry too much when you grind the gears - it happens from time to time and you'll probably do it again, just don't make a habit out of it and you shouldn't have anything to worry about.

The tranny is also closer to your ear than in most cars, without much between it and you to insulate sounds.

You didn't really grind the gears. That's a common misconception. The transmission gears are always engaged. Check this article out and you'll see what you did is no big deal:

When you make a mistake while shifting and hear a horrible grinding sound, you are not hearing the sound of gear teeth mis-meshing. As you can see in these diagrams, all gear teeth are all fully meshed at all times. The grinding is the sound of the dog teeth trying unsuccessfully to engage the holes in the side of a blue gear.
