well i went out and did a little playing with my truck and i got my G80 to kick in and lock. this is the first time the G80 has been locked ever on the blazer, i wouldnt think my grandma had it locked ever haha. is it normal to have a "finger nail on a zipper" sound when it locks? this noise is kinda loud and i got a little scared when i heard it. what have your experiences been with your G80?

 

mine works about 50% of the time. The clutches are wearing out. Mine doesn't really make any noise though

 

mine always kicked in, just makes that noise...kinda like screwing wood screws into a piece of hard wood...i could use a diff oil change tho

 

i would try changing the fluid and see if that helps. It could be the clutches are starting to go. Not sure though

 

i hope its not the clutches starting to go, its only got 49K on it and of that 43K were grandma driven
