I just put in a new tranny in. Drove it home noticed that it was making some odd noises whenever I let off the gas. It only makes the noise when I'm in gear or shifting. I think that the clutch isn't fully disengaging. It almost seems as though the tranny that I got is a pos.

 

Have you tried adjusting the clutch?

 

not yet. I was tired from working all day and put it in and drove home. I'll prob end up doing it today though.

 

yeah it sounds like its not disengaging. Try adjusting your clutch cable. It might be the clutch plate grinding on your flywheel. Does it have a sort of screeching sound? It could also be that you didn't adjust the clutch disc to proper specifications.
What stage is it?
