Your 2000 Toyota Tundra takes Dexron-IIiATF. If You don't routinely change Your fluids at least every 30,000 miles or so, You may find that Your transmission will slip. To change Your transmission fluid first park Your Tundra on level ground. It may help to raise it to gain easier access to the transmission.Remove all of the dirt and grease from around the drain plug. Let it drain. Then replace the drain plug. Add the new transmission fluid through the fill tube. It holds about 4 quarts. Replace the dipstick into the filler tube. Make sure to check the fluid level on the dipstick after the truck is warmed up.

To change the transmission fluid in a 2002 toyota tundra take the following steps: first, drain the fluid from the pan, just like you would using mr. Macfairlane's procedure. Once you've replaced the filter, the pan gasket, and reinstalled the pan, you're ready for the next step. Fill the transmission to the proper level using the proper type of transmission fluid. Then disconnect the return transmission line (the line in which transmission fluid flows from the transmission cooler back to the transmission), located near the bottom of the radiator. There's two transmission lines connected in this location, and the bottom line is usually the return line. Once the line has been disconnected, attach a clear piece of tubing to the transmission cooler, the same diameter as the transmission line, approximately 5-6 feet long, using the transmission line clamp to secure it. Place the unattached end of the clear tube in a plastic, one gallon milk container and place it where it can be seen (like not under the car). For the next portion of the procedure, make sure that the parking brake is set prior to continuing. Start the engine. The transmission may have to be put into "neutral" or "drive" in order to pump the fluid from the transmission. I usually put mine in "neutral" to accomplish this step. While the transmission is pumping out fluid, you can monitor approximately how much fluid has been pumped out by looking at how much fluid has been pumped into the plastic milk jug. While fluid is being pumped out, slowly add new fluid to the transmission at about the same rate as its being pumped out. This keeps the fluid level at, or near the proper level. You can see the condition of the fluid through the clear tubing as its being pumped out. After approximately 4 to 5 quarts (obviously, if it's more than 4 quarts, you'll have to turn of the engine, and fetch another milk jug) of fluid have been pumped out, you should notice a change in the color of the fluid. It should go from a brownish red color, to a bright pinkish red color. When this happens, all of the old fluid has been replaced with new fluid.
