Looking up information on limited-slip differentials when I came across this.

[Bluezone]

It seems GM offered a electronic limited-slip differential in it's version of the 6f55 transmission, the 6t80. I was kind of intrigued on how this worked and came across something posted by Dana. Kind of cool how it works.

Mind you they only use this Transmission in one car. Their version of the Taurus SHO and Lincoln MKS. Very similar engine specs size and weight to our cars. Hope your wallet is big if you want to try this particular car out though.

Cheers guys.
