Clean rags or paper towels
Transmission fluid dipstick (if applicable)
Torque wrench
Socket set and ratchet
Screwdrivers (Phillips and flathead)
Oil catch pan
Flashlight

Repair Instructions

Step 1: Address the Leak Source

Transmission Pan Gasket Replacement:
- Drain Transmission Fluid:
  - Place an oil catch pan under the transmission pan.
  - Remove the transmission pan bolts using a socket wrench and carefully lower the pan.
  - Allow the excess fluid to drain completely.
- Remove Old Gasket:
  - Scrape off the old gasket material from both the pan and the transmission surface using a gasket scraper, being careful not to scratch the surfaces.
- Install New Gasket:
  - Apply a thin bead of RTV silicone gasket maker (if required) to the transmission surface.
  - Place the new gasket onto the pan and align it properly.
- Reinstall Pan:
  - Reattach the transmission pan, ensuring it’s seated properly. Torque the bolts to the manufacturer’s specifications (usually around 10-15 lb-ft, but verify with a torque guide).
  - Refill the transmission with the correct type and amount of fluid through the dipstick tube.
Cooler Lines Inspection:
- Inspect the cooler lines for leaks or damage. If any lines are damaged, replace them.
- Tighten any loose fittings or connections.
Output Shaft Seal Replacement:
- If the leak is from the output shaft, remove the driveshaft (if applicable).
- Use a seal puller to remove the old seal and install the new one.
- Reattach the driveshaft and ensure all connections are secure.

Step 2: Refill and Test

Refill Transmission Fluid:
- Use a funnel to pour fresh transmission fluid into the dipstick tube. Check the owner’s manual for the correct fluid capacity.
- Start the engine and allow it to warm up. Cycle through all gears to circulate the fluid.
Check Fluid Level Again:
- With the engine running, check the fluid level again using the dipstick. Add fluid as necessary to reach the proper level.
Test Drive:
- Take the vehicle for a test drive, monitoring for any signs of leaks or abnormal shifting.
- After the test drive, inspect for leaks again.

Final Checks

Recheck fluid levels after a day of driving, adjusting as necessary.
Keep an eye on the transmission performance and look for any warning lights on the dashboard.

By following these steps, you should be able to successfully diagnose and repair a transmission fluid leak in your 2022 Chevrolet Silverado 1500 T1XX. If the leak persists or if you're uncomfortable performing these repairs, consult a certified technician.
