You mean that ECT button for the transmission? Hard to say - could be any number of issues - anywhere from an electrical issue (bad contact, broken or loose wire) to a bad transmission shift solenoid or worse. The ECT button just enables a different shift stategy for the transmission - allows the transmission to shift later and more eager to downshift.

First thing I would check would be switch itself - see if when the switch provides 12V to the ECU PWR signal line. Since the light is not coming on - this would rule out if it is a switch issue or wiring issue. If the switch provides 12V power to the ECU - then you potentially have problems with the shift solenoid in the transmission itself. If you had regular maintenace of the transmission fluid and used approved fluids - this would be a less likely scenario.
