Chevrolet Blazer transmission not shifting after new transmission and A/C replacement on Chevrolet Blazer

Some Chevrolet Blazer owners report experiencing transmission issues, such as the vehicle not shifting properly after a new transmission and A/C replacement. They highlight that checking the transmission fluid is crucial, as misaligned throttle position sensors and malfunctioning shift solenoids can contribute to these shifting problems. Additionally, odd noises from the transmission or engine area when the Blazer won't move in drive may indicate issues with gears, linkage, or other components affecting shifting. Symptoms of transmission problems in a 2019 Chevy Blazer can include the need to adjust the throttle cable, fix broken solenoids, reseal for leaks, and replace parts. Furthermore, many owners encounter the 'Shift to Park' error message, which can lead to strange electrical issues like an inability to turn off the electrical system, malfunctioning door locks, and a honking car horn. Low levels of transmission fluid or leaks, often caused by faulty seals, are also commonly reported problems. It is advisable for owners experiencing these issues to consult with a professional mechanic for proper diagnosis and resolution.
