Drain & Refill
The transaxle oil should be hot before it is drained. If the engine is at normal operating temperature, the transaxle oil should be hot enough.
- Raise the car and support it properly on jackstands so that you can safely work underneath. You will probably not have enough room to work if the car is not raised.
- The drain plug is located on the bottom of the transaxle and usually 24mm. Place a pan under the drain plug and remove it. Keep a slight upward pressure on the plug while unscrewing it, this will keep the oil from pouring out until the plug is removed.
- Allow the oil to drain completely. Clean off the plug and reinstall it, tightening it to 36 ft. lbs. (49 Nm).
- Remove the filler plug from the side of the transaxle case. Most Celicas should have a 17mm hexagon filler plug. It is on the front side. There is usually a gasket underneath this plug. Replace it if damaged.
- Fill the transaxle, with the proper lubricant, through the filler plug hole as detailed previously, using a suction gun. Refer to the Capacities Chart for the amount of oil needed to refill your transaxle.
- The oil level should come right up to the edge of the hole. You can stick your finger in to verify this. Watch out for sharp threads!
- Reinstall the filler plug and gasket, lower the car, and check for leaks. Dispose of the old oil in the proper manner.
Fluid Level Check
Only SAE75W-90 fluid or an equivalent should be used in the manual transaxles.
The oil in the manual transaxle should be checked at least every 15,000 miles (24,000 km) and replaced every 25,000-30,000 miles (40,000-48,000 km), even more frequently if driven in deep water.
- Park the car on a level surface.
- Raise the vehicle and support it properly on jackstands so that you can safely work underneath. You will probably not have enough room to work if the car is not raised.
- On some models it will be necessary to remove the LH engine under cover.
- Remove the 17mm hex filler plug from the front side of the transaxle housing.
- If the lubricant begins to trickle out of the hole, there is enough. Otherwise, carefully insert your finger (watch out for sharp threads!) and check to see if the oil is up to the edge of the hole.
- If not, add oil through the hole until the level is at the edge of the hole. Most gear lubricants come in a plastic squeeze bottle with a nozzle; making additions simple. You can also use a common everyday kitchen baster.
- Replace the filler plug and tighten it to 36 ft. lbs. (49 Nm). Run the engine and check for leaks.
