Changing the transmission filter on your Honda car is not a regularly scheduled maintenance item. If the automatic transmission filter has been contaminated or leaking, if the transmission is being overhauled or replaced, you should change the filter. Most Honda car have in-line filters located within the transmissions that are fairly simple to repair. Draining and refilling the system is required to maintain a clean and properly functioning transmission.

 How to Change the Transmission and Filter in a GMC Yukon XL

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.

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.

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.

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.

 How to Change the Transmission Filter in a Honda Accord

Drive the vehicle around for about 15 minutes to warm up the fluid. This causes it to become thinner and more easily drained. Apply the parking brake and put blocks of wood behind the rear wheels. Using a floor jack, raise the vehicle's front end. Place jack stands under the vehicle on both sides of the frame. Secure the immobility or movement of the vehicle in order to provide a safe working area.

Put the spill pan under the transmission directly beneath the drain plug. Remove the splash shield and use the 17-mm socket to remove the fill plug. Then use the 3/8-inch ratchet to remove the drain plug. Drain the transmission fluid and replace the drain plug when all the fluid has leaked out. Use a new sealing washer when reinstalling the drain plug.

Disconnect all cooler hoses from the filter. Remove the filter holder and the filter itself. Install the new transmission filter and tighten it using the holder and bolt supplied.

Reconnect the cooler hoses to the filter and secure them with the clamps provided. Reinstall the splash shield. Refill the transmission with Honda premium automatic transmission fluid or an equivalent fluid per your vehicle's manufacture's specifications.

Start the vehicle and shift through the gears. Put the gear in park and turn off the motor. Check the level of transmission fluid on the dipstick. If the level is between the two marks on the dipstick, the correct amount of transmission fluid is in the system.

 How Do I Change the Transmission Filter on a Hyundai Accent?

Remove the Transmission Filter

Warm up the engine for about five minutes before draining the oil. This will help the oil wash all the metal, dirt and friction particles accumulated throughout the transmission and flush them out. Then you can drain the oil by raising the front of the Hyundai, supporting it on a couple of jack stands and removing the drain plug on one side of the oil pan at the bottom of the transmission.

When taking the oil pan off, first unscrew and remove the side and front mounting bolts using a ratchet, ratchet extension and socket. Then carefully loosen and remove the back mounting bolts as you hold the pan with a shop rag. Tilt the pan on the catch pan to drain the remaining oil. When finished, take the pan out of the vehicle. Now you will see the filter at the bottom of the transmission. Unfasten the four mounting screws using a standard screwdriver and remove the filter.

Install the New Transmission Filter

Install the new filter and secure it with the four mounting bolts but do not over tighten. Thoroughly clean the oil pan and the transmission gasket surface. Use a new gasket for the oil pan. When mounting the oil pan, start the bolts by hand and then tighten them in an evenly and crisscross pattern. Avoid over tightening the bolts here as well, or you will destroy the gasket and end up with a leak.

After lowering the vehicle, refill the transmission with the transmission oil type recommended by the car manufacturer for your particular model. Check the car owner's manual, if necessary. Then start the engine and shift the transmission through all the gears. Finally, set the transmission to "Park," turn off the engine and check under the vehicle for oil leaks.
