Automatic Transmission - 4l60e linkage cable or tranny problem

I need someone help .... Plz . I drive a 2002 gmc Yukon 2WD non XL... With a 5.3. I just replaced the tranny and now I don't have a reverse, it doesn't go into park, can't rev my engine it sounds like it's hung. Drive works but sounds like I have a very big stall then it gets going. I have many more problems. And I need help please

U need someone local to u, sounds like more than 1 issue. Did u by chance drop the trans with convertor during install?
