Speed Sensor Removal on 1999 Mercury Sable

:banghead: Anyone have tips for removing a speed sensor from a 1999 Mercury Sable with a Duratec V6? I removed the hold down bolt and pulled the sensor but the top pulled off leaving the speed sensor metal shoulder and gear inside the transmission. The car was driven on salty roads and the sensor seems to be frozen in place. I've soaked it with WD-40 but still not loose. I've removed the motor mount to get better acc. Are there any special tools to get around the shoulder? Please Help!

Fixed, remove Passenger tire right motor mount and use small channel locks to rotate and pull sensor. Thanks!
