The drain plug at the tranny from driver side near the drive axle.
The transmission drain bolt for 1997 to 2000 toyota corolla.
See fig below:--
There is only 1 plug to check, and the other to drain. Make sure you open the fill plug first to make sure you can add fluid, before you drain it, and either round out the bolt, or realize it seized and your stuck with a drained trans. Also, only fill it with the specified 75-90w oil, use of a thicker oil can make shifting into first tough when the trans is cold.
