I can't find anywhere in owners manual where it says when to change the fluids in differential and transmission. Can someone tell me where to look?

I think that they are part of the Maintenance I and Maintenance II plans. I worked at a service shop in high school and it was always 15k for the diff and tranny fluids...although GM claims that the transmission is filled for life meaning you never have to change it....NOT TRUE

It recommends that the transmissoin and differential fluids be changed every 50k miles IF the vehicle was used for "high performance operation." DUH!

It also has a footnote that says to change the fluid after the vehicle has been driven for 3,000 miles with the transmission temperature above 290 F or higher.

Check pages 6-4 through 6-9 of the owners manual.

I am doing mine every other oil change. About every 10k miles
