At what mileage should these be changed? I have 58,000 miles on my 2002.

honestly on these new 4l60e 70 80e etc id change at 10k miles like i allways do. Just to be on the safe side.

(This is the TB SS forum, not the regular TB one FYI.)
I changed my ATF filter and pan fluid (5qts) at 50K last July. I am planning on installing a tranny cooler here in the next month or so and will completely flush the entire system and replace the filter at the same time. I am at 60,1xx mi now and will probably have about 61K before long (possible trip next weekend).
I also changed the differential lube and the transfer case fluid (only use GM AutoTrak II, only one that works in the case) at the same time.

You can do partial ATF swaps as often as you can stand, but for normal driving, every 30-40Kmi is ideal. LOTS of towing or offroading & I'd do it every 12-15Kmi.
