    OK, Before I order my Shift-kit tommorow, I want to know exactly what transmision I have on my 2004 silverado RCSB 5.3L, is it the 4L60E or what? Some one tell me soon so I can order it tommorow. Thanks

    You have the 4L60-E.

    I don't know what's all involved in upgrading it but there is also a HD version of that tranny, the 4L65-E as found in the Silverado SS, Escalade, etc.
