RUDY, the part in your transmission was hopefully the Vehicle speed sensor. From what I understand, most of the failure on the Toyota's is actually the instrument cluster itself. Do go ahead and check your connector. That way at lest you know that the sensor and the harness are okay.\:" INSPECT VEHICLE SPEED SENSOR

(a) Connect the positive (+) lead from battery to terminal 1 and

negative (–) lead to terminal 2.

(b) Connect the positive (+) lead from tester to terminal 3 and

negative (–) lead to terminal 2.

(c) Revolve shaft.

(d) Check that there is voltage change from approx. 0 V to 11 V

or more between terminal 3 and 2.

HINT: The voltage change should be 4 times per each revolution

of the speed sensor shaft.

If operation is not as specified, replace the sensor.

If that should check out, you know it is not the sensor. then go ahead and check the connector to your instrument cluster

or the harness, you can check the instrument cluster using the wiring diagram.

If all those points check out okay, I definitely would repair or replace the instrument cluster. Hope this helps, good luck
