Filthy Transmission Fluid After 110,000 Miles

There’s a heated debate among car enthusiasts and mechanics about whether changing the Transmission fluid and filter in a 6l80 transmission after 100,000 miles is a wise move or a risky gamble. On the one hand, proponents argue that fresh fluid and a clean filter can rejuvenate the transmission, enhancing performance and longevity by removing old, degraded fluid and contaminants that could otherwise lead to wear and tear. But here’s the kicker: others staunchly believe that changing the fluid at this point can dislodge debris and actually cause more harm than good, potentially leading to transmission failure. This is on my 2018 Chevy Silverado. So, what’s the real answer here? Is it safer to stick with the old, original fluid, risking increased friction, heat, and clogged filters that might cause the transmission to slip or shift erratically? Or is it better to take the plunge and refresh the system despite the fears of stirring up trouble inside the transmission? Are there experiences out there where changing the fluid after so many miles has either saved a transmission or doomed it? What do you think is the real risk-benefit balance here?
