The axle and driveshaft are critical components that transmit power from the engine to the wheels.
If one of these parts breaks, power cannot reach the wheels, rendering your truck immobile when you put it in Drive.
If your Silverado isn’t moving, visually inspect the axle and driveshaft for any obvious signs of damage.
However, keep in mind that not all damage will be visible without a detailed inspection, so it might be necessary to consult a professional mechanic.
Should a broken axle or driveshaft be the cause, the solution is to replace the damaged part.
This is a complex job that requires specialized tools and knowledge, so it’s usually best left to professional mechanics.
#3- Transmission Failure (Bad Solenoid, Valve Body, Clutch Pack)
Various components within the transmission, such as the solenoid, valve body, or clutch pack, can fail and cause your Silverado to refuse to move in Drive.
These parts are responsible for controlling the flow of transmission fluid and shifting gears.
Troubleshooting these issues often involves using a diagnostic scan tool to look for error codes in your vehicle’s computer system. These codes can indicate which component is at fault.
However, diagnosing transmission problems can be complex and is often best left to professionals.
If a part within the transmission is faulty, it will need to be repaired or replaced. This typically involves removing and disassembling the transmission, which is a labor-intensive job best done by professionals.
After the repair, the transmission fluid should be replaced, and the system should be properly sealed to prevent leaks.
#4- Faulty Speed Sensors
Speed sensors provide essential data for your vehicle’s computer system. They measure the speed at which the wheels are spinning and send this information to the computer, which uses it to control various aspects of the vehicle’s operation.
If these sensors fail, they can cause a range of problems, including issues with moving in Drive.
Troubleshooting this issue often involves using a diagnostic scan tool to look for error codes related to the speed sensors. If a fault code is present, it can indicate which sensor is problematic.
If a speed sensor is faulty, the solution is to replace it. Depending on the specific sensor’s location, this can be a relatively straightforward DIY job, or it might require the expertise of a professional mechanic.
#4- Truck Stuck In Park Due To A Problem With The Shift Interlock Solenoid
The shift interlock solenoid is a safety feature that prevents the vehicle from being shifted out of Park unless the brake pedal is pressed.
If this solenoid is faulty, the truck might be stuck in Park, causing it to refuse to move when you shift to Drive.
Troubleshooting this issue involves testing the shift interlock solenoid’s operation. This can be done by checking if the vehicle can shift out of Park when the brake pedal is pressed. If it can’t, the shift interlock solenoid might be at fault.
If the shift interlock solenoid is faulty, the solution is to replace it. This is a relatively straightforward job that most mechanics can perform relatively quickly.
However, it’s essential to use a replacement part that’s compatible with your specific Silverado model to ensure proper operation.
#6- Burned Up Differential
A differential allows your vehicle’s wheels to rotate at different speeds, particularly when turning. If the differential is burned up or damaged, it can prevent your Silverado from moving in Drive.
