techinically, this corolla is known as ae-101, automatic. wether its se, gl, xe.
the gearbox oil chk dipstick is right behind radiator, not far from distributor frt top of gearbox unit., seems like a sensor issue to me, un-usual problem, you didnt show how many miles on odometer, does this happen in winter or summer also. could be wrong grade oil. make sure oil you used match the specs on picture below.
