So I recently rebuilt my transmission, new clutch, guibo and it's been great. The other day, I think I was going from reverse to first and the car made a strange "Squack!" It's a funny sound that I believe I've heard come from cars before. Hard to describe, maybe what it would sound like it a giant person stomped on a goose (sick image I know). Anyone know what might have caused that?

Did you have too much Taco Bell for lunch that day?

Could be anything from motor mount to difrential or even the Guibo. Was it old stock or a new one? New old stock rubber products can fail pretty quickly if they were not stored properly.
