How to Fill Automatic Transmission Fluid in a 1990 Toyota
- 1). Start the car and allow it to warm up. This will involve letting it run for five minutes. Slowly move the gear shifter from "Park" all the way down to "Low 1." Move it back to "Park" and set the parking brake.
- 2). Open the hood to access the engine compartment. Locate the transmission dipstick. The dipstick tube will be located behind the engine. Pull the dipstick out of the tube and wipe it off with a fresh rag. Insert the dipstick back in to the tube.
- 3). Pull the dipstick back out of the tube and check where the fluid level stops on the end of the dipstick. There will be markings on the dipstick. The bottom marking will represent a low level and the marking higher up on the stick will designate a full level. If the fluid is in between the markings, then the level is safe. If the fluid is below the bottom marking, it is time to add transmission fluid.
- 4). Insert a funnel on to the dipstick tube. Pour in half a quart of transmission fluid. Check the level by removing the funnel and inserting a clean dipstick into the tube. Continue filling until the level is on the full mark on the dipstick.
- 5). Insert the dipstick and dispose of the funnel. Close the hood.
