Is it that optional Eaton rear end that has been praised in tests against its foreign rivals who don't offer the same kind of traction when the going gets rough.

i have an 07 colorado 4x4 . Window sticker reads auto locking rear diff.. I'v never heard any noise and it always leaves 2 nice black marks w/ 265/75/16 tires in 2 wheel drive on hard takeoff.

Can I purchase a g80 locking differential for my 07 Colorado on line?

The automatic locking differential on the canyons/colorados is designed to sense a loss of or lack of traction at ONE wheel versus the other and will lock at the time that those preset parameters are reached.
 
It doesn't have anything to do with whether or not you can lay down 2 stripes of rubber on the road.
 
The automatic locking differential also will REDUCE available engine power when it is actuated. It works good BUT there are times when a locked axle & full available power can be an asset.
 
There needs to be a module mod to allow full power with the axle locked.

Just a bit of info for you. Your service manager needs to do better home work and better research. This is way better than a "posi trac". It is a true locker that uses a clutch setup to lock up when the rear senses slippage from one wheel. I have a 2005 with the same rear end, and it has not given me any trouble. I sell these trucks for my living, so I do know what I am talking about.

Actually the comment about the reduced power availability to the engine has nothing to do with the Diff. That is the traction control unit, and if your truck has the traction control it can be turned off via the switch on the dash above the radio. As for two strips of rubber, you are right in some situations. If you were to be on flat pavement it would have nothing to do with it, but if you were to encounter, lets say a curb, and both wheels kept laying down rubber, then that would be the locker locking up. Let me clarify that a bit, if just one wheel contacts the curb, thus changing the number of rotations that one wheel makes in relation to the other, because the wheel going over the curb is actually traveling further than the one on the flat pavement, the situation I have described happens.
