The FEL PRO TOS 18687 gasket arrived just in time for me to install before a track day. Based on my experience, this gasket improved my car's shifting performance and eliminated any transmission leaks. The fit was perfect and installation was easy, even for a novice like me. The only con I have is that the price is a bit high compared to other gaskets on the market, but the improvement in my car's driving experience makes it worth the extra cost. Overall, a great investment for any performance car enthusiast.
