My transmission issending out a buzzing sound. Mainly in park and neutral, it does it some in drive but not at all in reverse. Anyway, I think it is an FMX...not sure but I checked the fluid and that is OK. Oh yea, it has a shift kit in it, don't know if that matters or not. Any ideas?

 

Exactly where is the buzzing coming from? Is it from the shifter, or inside the transmission? If the shifter is buzzing there is a kit that will stop it.

 

It is coming from under the car so I would assume inside the transmission itself. I am not 100% sure but I will check.
