2004 Sierra 1500 - Transmission Issue

Transmission works good when it's cold but loses gears once warmed up. Would changing the fluid correct this? Fluid last changed 90K ago...

yea, i would try changing the fluid for sure...that's at least 3 times longer than you sld ever go on a tran-fluid change.
