The 2018 GMC sierra does have adaptive cruise control. The transmission fluid needs to be replaced every 30,000 to 60,000 miles. Along with fluid changes, terrible sounds will come from the transmission. Old transmission fluid will be awful to the ear. A worn out torque converter will cause a headache. The transmission is one of the most crucial parts of the vehicle. You will come into issues at some point. Delayed shifts will cause acceleration issues. The transmission might slip. You could experience shudders. Hard shifts could arise and that is not good. There may be jerking. The gears might become stuck. If the transmission fluid leaks, that needs to be fixed quickly.
