In fact, TrailBlazer speedometer problems are one of the most common topics discussed on popular Chevy online forums.
How does the Transmission Control Module ( TCM ) work?
The transmission control module (TCM) is the computer that controls your vehicle’s transmission. Various sensors provide input to the TCM. It then uses this information to determine control of various outputs, such as the shift solenoids and torque converter clutch solenoid.
What to do if your speed sensor is not working?
Have an auto parts scan for codes to see if your speed sensor has gone bad. They scan for codes for free. If not it may be a tcm problem as well at least for the shifting part on your trans. However with your mileage it may be an internal trans problem or a wiring issue as well.
What to do if your speedometer doesn’t work?
Replacing the bad speed sensor will solve this issue. Also, if speedometer in your Chevy stops working or reads erratically, test the cruise control out. The cruise control uses the same sensors as your speedometer. If the cruise is working and the check engine light is on, the problem is likely with the speedometer itself.

Where is the speedometer located on a car?
Where is the speedometer sensor located? The speedometer sensor is located in the transmission of your vehicle and is designed to register the driveshaft’s rotational speed. The sensor delivers this information through the speedometer cable and to the vehicle’s computer, which converts electrical pulses into a numerical speed.
