Topic: Strange tranny noise

[toymachine]

I have a mini with i think an 82 five speed in it.  I am getting this rattling sound when i bring the rpms around 2500 and higher. Its through all of the gears and reverse too.
Does anyone know what this could be.  I did just put 4.70 gears in my transfer case, but i think it was making the n oise before i did that.

just a guess,,possibly the pilot bearing is shot letting the imputshaft move..I have never been into a toy trans but that woud be my first guess due to the fact it does it in all gears..
