you have the 4t65E. 
4t60 was the transmission used before 1997. I think you're confusing what the NA bonneville gets and the supercharged version. 
The Supercharged Bonneville 97+ has the 4t65E-HD. The NA is the 4t65E. The GXP Bonneville has the 4t80E.

Has anyone tried to hook the 4T80E from the GXP up to an SSEi that came with the 4T65E-HD? My tranny(?) has been acting up with some chuggle and if worst comes to worst I'd like to know my options. Would it be possible to replace my 4T65E-HD with the GXP 4T80?
