They are supposed to have a 4T65E-HD.
There are lots of racing components for those transmissions and there is even a racing guidebook that was published by GM Racing.

You can download the manual from the link shown below.

There used to be some HiPo parts available when GM was supporting the Sports Compact program . That was a long time ago , and there are none of Engineers that used to work in that group left working at GM .
