Abstract
The present invention provides an automatic transmission control apparatus which comprises a first temperature detection device for detecting a temperature of hydraulic oil stored in an automatic transmission; an automatic transmission control device installed in a same casing as that in which the hydraulic oil is stored; a second temperature detection device for detecting a temperature of the automatic transmission control device; and a malfunction determination section for comparing the temperature of the automatic transmission control device detected by the second temperature detection device with the temperature of the hydraulic oil detected by the first temperature detection device to determine whether or not a malfunction occurs in the first temperature detection device.
