How to Change the Transmission Filter in a Silverado
- 1). Park the Silverado on a level surface and engage the parking brake. Lift the truck with the jack and set jack stands underneath all four corners. Lower the jack so the weight of the truck is supported on the stands, and you have enough room to work underneath the vehicle.
- 2). Put the drain pan below the transmission pan. Remove the drain bolt in the center of the transmission pan using the 3/8-inch ratchet and socket, and allow the fluid to drain into the pan. Then unbolt the transmission pan from the bottom of the transmission using the ratchet. You may have to unbolt the heat shield on the catalytic converter with the ratchet or the shift linkage on the opposite side using the same tools.
- 3). Pull the large black transmission filter off the transmission with your hands. Clean off any remnants of the gasket from the transmission pan and the bottom of the transmission. Reinstall the drain pan using the ratchet, including the catalytic converter heat shield and shift linkage if necessary. Lower the truck off the jack stands using the jack.
- 4). Open the hood. Locate the transmission dipstick, which has a yellow handle and is mounted on the passenger side of the engine. Remove the dipstick and install a funnel into the tube. Pour 4 qts. of automatic transmission fluid into the funnel and then reinstall the dipstick.
- 5). Start the Silverado. Run the engine at 4,000 rpm or so with the vehicle in "Park," for approximately two minutes. Cycle the gear selector through each gear with your foot on the brake, then let the engine idle in park for five minutes. Recheck the transmission dipstick, and add fluid if necessary.
