Chevy Silverado 1500 warns against flushing the transmission
Unfortunately, transmission problems with the Chevy Silverado 1500 are so common that dealerships like Granger Chevrolet share the warning signs.
Issues such as leaking transmission fluid, dirty/burnt transmission fluid, shift flares, hard downshifts, jolting, whining noises, and failure to shift into gear can be signs of failure.
Upon listing what to look out for, many dealerships offer to inspect the six-speed, eight-speed, and 10-speed transmissions for you. They also offer to repair them.
However, a common repair involves flushing the transmission, and experienced Chevrolet drivers warn against this process.
According to Torque News, flushing the transmission can force fluid through it with high pressure. It can clear debris, but it might also dislodge pieces of metal and dirt that can get stuck in critical pieces.
For example, it might get stuck in the solenoids or valve body, making the transmission perform worse than before.
Instead, it’s recommended to drain the transmission fluid, clean the pan, and replace the filter. Then fill the fluid to the proper level. These steps often help the transmission get back to proper working order.

These steps can help prolong the life of the transmission. It might prevent expensive repair bills or having to replace it.
However, owners should also be aware that General Motors has been facing class-action lawsuits over alleged faulty transmissions in vehicles from 2015 to 2019.
While most trucks don’t experience transmission problems until surpassing 100,000 miles, some Cadillac, Chevrolet, and GMC models face issues early on.
For example, the transmissions may fail before reaching 40,000 miles. One owner of a 2024 model experienced transmission failure at 594 miles.
