I have a very nice 99 TA that has 158K miles. The original LS1 is running very strong still, but I have a line on a LS2/4L65E swap from a GTO. The LS2 is a new GM warranty replace and then the guy totaled his GTO. What will be needed to make this swap work. I did a quick search and didn't really see anything. The LS2 will come with everything.

 

After doing a more direct Google search, I found it... seems the LS1tech search is not as good as google... lol
