How to Check Transmission Fluid on 2007-2013 Chevy Silverado

The 2007-2013 Chevy Silverado models have a 6-speed automatic transmission (6L80 or 6L90) that requires a dipstick to check the fluid level.

Here are the steps to follow:

  • Warm up the engine by driving for about 15 minutes or until the engine reaches normal operating temperature.
  • Park on a level surface and apply the parking brake. Keep the engine running and shift through all the gears, pausing for a few seconds in each one.
  • Shift back to park and open the hood. Locate the transmission dipstick at the rear center of the engine compartment. It has a red handle and a yellow label that says “TRANS FLUID”.
  • Pull out the dipstick and wipe it clean with a lint-free cloth. Reinsert it fully and pull it out again. Check the fluid level on both sides of the dipstick. It should be between the hot cross-hatched area or the upper hole.
  • If the fluid level is low, add some DEXRON-VI fluid through the dipstick tube using a funnel. Do not overfill. Check the level again after adding some fluid.
  • If the fluid level is okay, check the fluid condition. The fluid should be red or pink in color and have a smooth consistency. If the fluid is dark brown or black, smells burnt, or has particles in it, it may need to be changed.

How to Check Transmission Fluid on 2014-2019 Chevy Silverado

The 2014-2019 Chevy Silverado models have an 8-speed automatic transmission (8L90) that does not have a dipstick. Instead, you need to use a scan tool or an app to read the transmission fluid temperature and a fill plug on the side of the transmission to check the fluid level.

Here are the steps to follow:

  • Warm up the engine by driving for about 15 minutes or until the engine reaches normal operating temperature.
  • Park on a level surface and apply the parking brake. Keep the engine running and shift through all the gears, pausing for a few seconds in each one.
  • Shift back to park and open the hood. Connect a scan tool or an app to the OBD-II port under the dashboard and read the transmission fluid temperature. It should be between 160°F and 200°F.
  • Raise and support the vehicle safely using jack stands. Locate the fill plug on the passenger side of the transmission near the oil pan. It has a hex head and a blue seal.
  • Remove the fill plug carefully using a 3/8-inch drive ratchet or wrench. Some fluid may come out. If no fluid comes out, add some DEXRON-HP fluid through the fill hole using a hand pump or a syringe until it starts to drip out.
  • Reinstall the fill plug and tighten it to 18 ft-lbs using a torque wrench.
  • Lower the vehicle and turn off the engine.

How Often Do You Check Your Transmission Fluid?
