Can someone link me to what transgo shift kit i need for my 2004 GP GT. I know its the 4t65e but on some of the ebay ads it says that it requires transmission removal and cannot be installed via the lower pan.

If im not mistaken, my car's (2004 GP GT) valve body is accessible via the lower pan?? Im not sure if they are referring to other vehicles that take the same kit or not. Figured I would ask the experts here :-)

Also, Canadian links would be nice but not a necessity

Thanks in advance!
