Your welcome 54 oldsman!
You should consider replacing the sensor though because the damage has been done and just blowing out the moisture is just a temporary fix. Also, the sensor may have been updated by Ford for your year of truck. If the connector is a "D" shape then there is an update, if it has an oval shape it just needs replaced. If it needs updated, there is also a new wiring connector kit that goes with the sensor.
I am assuming that there was moisture found in the connector.
When you get the trans serviced, make sure they use the Ford trans filter. This filter seems to stay in place better thatn the after market. You can also purchase a new pan that has a drain plug installed inn it from Ford with a reusable trans pan gasket and matching pan bolts, this way your next service will be that much easier. Get a pan that is from a 99- 4R100 trans, they come with a drain plug which makes dropping the pan a snap.
