Does any body know if the Bolt Differential is shared with any other GM platform, I was wondering if there was the possibility if it was shared with something like the sonic to lend possibility for a limited slip unit.

The Bolt is a Trax, you would need to scope out the mounts and other goodies to see if it roughly fits anything else.

ive never seen a tear down of the transaxle , spline and other components would need to be identified

A Trax, or Sonic, or Spark, or any of the GM Gamma II platform vehicles could share this component. On the other hand there are so many differences between the Bolt's transaxle and the transaxles used in the other vehicles on this platform (at least two different manuals and at least two different automatics) that it isn't at all certain that the differentials are shared. Because the Bolt is more powerful than any engine in any Sonic or Trax, it's possible that the differential is from a differents parts bin, shared with a larger model.

Bearing diameters and spacing, output splines, ring gear bolt circle diameter... there are a bunch of critical dimensions if comparing potential differentials. A complication is that one output of the Bolt diff is inside the hollow motor shaft, which changes the bearing configuration on that side - you can see the very large diameter bearing on that side at about 24 minutes into the video.

The GM 6T40 seems like the most likely transmission to share components with the Bolt, since it is used in Gamma II vehicles and is also used in much heavier cars so it should be able to handle the Bolt; the 6T35 is also a possibility, and may use the same differentials. The Ford 6F35 is apparently the same design; the diff might be interchangeable but that's far from certain.

There are a few companies that make lsd's for any diff, they can tell you if dimensions are shared with any other part.

In this video Kelley has the drive unit all laid out and explains that it is a one speed trans. As such no gas car is going to share this drive.

That wasn't clear to you from post #4?

The whole transaxle is not shared with any other model, but the differential could be; however, as I mentioned, due to the bearing configuration resulting from the coaxial design, it likely that it's not shared with anything.
