If the check light came on about the time the gauge quit then there probably is a problem with the sensor or its wiring. This can be confirmed if there is a transmission check switch which you hold in the "on" position with the ignition on. The check transmission light Wil flash a code. If it is code 22, then the ECU is saying it has a problem getting reliable output shaft speed.
You can check for a wiring problem by measuring the resistance between the two contacts in the top row of the J1B connector in its right corner. The J1B connector is is the upper right one when facing the connector end of the ECU. The resistance be 115-165 ohms including the sensor.
According to my manual the sensor is not adjustable on on-highway transmissions.
