How to Change the Transmission Fluid in a Toyota Supra
- 1). Park the Toyota Supra on a even surface and pull the emergency brake up.
- 2). Slide the jack under the front of the Toyota Supra and jack it up. Put the jack stands under the frame rail on both sides of the car. Make sure that the jack stands are under the frame rail behind each front tire.
- 3). Slide under the front of the Toyota Supra and locate the transmission pan. The transmission-fluid pan is located on the very bottom of the transmission. The transmission drain plug is on the driver side of the transmission right above the transmission-fluid pan. The transmission-fluid fill plug is located on the driver side of the transmission near the top.
- 4). Slide the transmission-fluid catch pan under the drain plug on the driver side of the transmission. Remove the drain plug with the ratchet and socket. Wait for all of the transmission fluid to drain out and then screw the transmission drain plug back into the driver side of the transmission. Tighten the drain plug with the ratchet and socket.
- 5). Slide the transmission-fluid catch pan out from under the Toyota Supra and go over to the passenger side of the car. Crawl under the passenger side of the Supra and locate the transmission-fluid fill plug. The fill plug is located near the top of the transmission on the driver side. Remove the fill plug with the ratchet and socket.
- 6). Slide one end of the plastic tube into the fill hole and the other end of the plastic hose onto the fluid pump. Pump the 80/90 gear oil into the fill hole until the gear oil runs out of the fill hole.
- 7). Crank the engine and check the fluid level inside of the fill hole with the engine running. If the gear oil level stabilizes at the top of the fill hole, then the transmission is full. If the gear oil level drops below the fill hole with the engine running, you will need to add more gear oil until the gear oil stabilizes at the top of the fill hole. Then, turn the engine off.
- 8). Screw the fill plug back into the fill hole. Tighten the fill plug with the ratchet and socket.
- 9). Jack the front of the Toyota Supra up and slide the jack stands out. Lower the Supra to the ground. Job complete.
