How to Change the Transmission and Filter in a GMC Yukon XL
by Matt Scheer
According to the Haynes Repair Manual, the GMC Yukon XL needs to have the transmission fluid and filter changed every 30,000 to 40,000 miles or every two years (whichever comes first). If the Yukon is being used frequently for towing, this increases to every 20,000 miles. Changing the fluid is necessary to keep the gears from grinding and prevents overheating. This regularly scheduled maintenance keeps the car going longer and requires only a few tools.
Step 1
Raise the front two wheels of the Yukon on a pair of jack stands to gain easier access to the underside of the engine. Slide underneath the car, and look for the transmission drain pan in the center, toward the driver's side. The drain pan is a large, metal tank, surrounded by eight bolts. Place a collection pan beneath the drain pan.
Step 2
Remove seven of the eight bolts with the 1/2-inch socket wrench. Allow the fluid to drain from the pan for 10 to 15 minutes, until it stops pouring from the edges of the pan. Hold the pan in place with one hand, and remove the final bolt. Lower the remaining fluid into the collection pan. Wash out the pan and the bolts.
Step 3
Remove the three bolts fastening the transmission filter into place beneath the drain pan. Place the new filter on the transmission, and replace the bolts. Reattach the drain pan. Lower the car from the jack stands.
Step 4
Open the hood of the Yukon, and find the yellow transmission dipstick above the drain pan. Pull it out, and place a funnel into the tube. Pour in four quarts of transmission fluid. Replace the dipstick, and close the engine hood.
