Is the Whine really the differential?

Remove this ad
Ok, So i have had my diff replaced for whining before and now I am begining to wonder.

I have 6th gear whine now. Whenever I am in 6th gear between 55-65 I get a whine. This is a known issue at GM and there is a TSB on it (thanks for that Barak). I am going to see what they say about this next week.

Bottom line: I am wondering if people are going in with actual transmission issues and telling the dealer that the rear is whining. This could be due to everyone here drawing attention to the diff when it may actually be the tranny...

This is an obvious exception to those of us who had Diff whine and have cracked the differential housing.

It seems that more of us are having severe transmission shifting issues than differential issues (wait for the survey results I am posting tonight).

Could the tranny be the bigger issue here?

Anyone care to comment?
