Issue: 2022 Chevrolet Silverado 1500 T1XX Not Shifting into Gear

Tools Required:

• OBD-II scanner
• Multimeter
• Transmission dipstick
• Socket set
• Screwdrivers
• Transmission fluid
• Funnel
• Torque wrench

Repair Instructions:

1. Fluid Level Adjustment:

   • If the transmission fluid is low:
     • Use a funnel to add the appropriate transmission fluid through the dipstick tube until it reaches the correct level.
   • If the fluid is dirty:
     • Drain the transmission fluid using a socket set to remove the pan bolts.
     • Replace the filter and gasket, and refill with new transmission fluid.

2. Replace the Transmission Range Sensor:

   • Disconnect the battery to avoid electrical shorts.
   • Locate the transmission range sensor on the transmission housing.
   • Remove the connector and unscrew the sensor using the socket set.
   • Install the new sensor and reconnect the battery.

3. Test and Replace Shift Solenoids:

   • If testing reveals a faulty shift solenoid:
     • Remove the transmission pan to access the solenoids.
     • Disconnect the electrical connectors and remove the affected solenoids.
     • Install new solenoids and reassemble the transmission pan.

4. Reprogram the TCM (if necessary):

   • If the TCM is replaced, it may require reprogramming with a scan tool to sync with the vehicle’s computer system.

5. Final Checks:

   • Clear any DTCs using the OBD-II scanner.
   • Start the vehicle and attempt to shift through all gears to ensure proper operation.
   • Test drive the vehicle to confirm the issue is resolved.

Conclusion:

If the vehicle still does not shift into gear after performing these steps, it may indicate a more severe internal transmission issue, requiring professional diagnosis and repair. It's recommended to consult with a certified transmission specialist for further assistance.
