Hello All

I have a 2012 Autobiography with 102K. Apparently the transmission spline going from the transmission to the transfer case is stripped. I have it at a transmission shop and am trying to find a replacement but the problem is(as you probably know) these transmissions are so specific to the car from the factory it is almost impossible to find an exact replacement. That leaves me with trying to rebuild the tranny. I have found some good rebuild kits HERE but I can't find the actual spline that goes from the tranny to the transfer case.
Who here has had to dealt with this?
Any help would be greatly appreciated ....
