2000 silverado 2500 overdrive??? So I bought my truck in Eastern Kentucky and drove it all the way to South Central Kentucky no issues whatsoever 2 Days Later I noticed that it kicks into overdrive around 50-ish miles per hour and as soon as it kicks into overdrive it kicks right back out of overdrive. The transmission shop said it was an output speed sensor and they replaced it and a week later the same problem has happened.it's extremely annoying however when it kicks out of overdrive I can shift down to 3rd gear and drive fine except the RPM. The transmission shop told me they have no clue what's going on...6.0 4l80e
