Usually I like to help by giving answers but got a question about the trans after a very stupid thing I did. I got cut off the other day and took off after the person and blew the shift from 3rd to 4th and got 2nd instead and it was a quick shift like back in the race days. RIGHT!! I damn near over revved the engine but now have a very slight wub wub sound from what sounds like from the gear on the final front diff. It only makes it after the trans has warmed up and is constant to tire RPM and will change tone very slightly as the gas pedal is varied. I wonder if I shouldn't worry about it unless it gets worse or change out the trans with my spare that I was going to do a 6 speed mod and never got to it. I fell like a idiot for doing what I did and if I didn't tell anyone riding in the E they wouldn't know by how quiet it is. It almost sounds like a tire has a cupped spot on it other then the level of the sound changing to the gas pedal movement.
