Hi Guys!

I recently bought a stock Integra Type S, and it's been amazing!

However, I have noticed a few issues with it:

3rd Gear keeps grinding when you shift hard. I tried looking this up, and it looks like it's a common problem, however, cannot find a solution to it. I've been told if you change the tranny oil, it might solve the issue, but don't know what oils to use? any suggestions? OEM or non OEM brands? which ever has worked from other owners?

The rear tail lights keep fogging up, is there a way to solve this? i.e. replacing the seals?

This has been driving me insane, so many thanks in advance!!
