How do you check transmission fluid in 2004 Lexus gx 470?

To check the Transmission Fluid in a 2004 Lexus GX 470, start by warming up the engine and letting it idle. With the vehicle in park, locate the transmission dipstick, which is usually found near the back of the engine bay. Pull out the dipstick, wipe it clean, reinsert it fully, and then remove it again to check the fluid level. The fluid should be within the marked range on the dipstick; if it’s low, add the appropriate type of transmission fluid as specified in the owner’s manual.
