A speed sensor shouldn't cause that. Make sure the trans fluid is clean and full. After that, if the check engine light has come on, have the computer scanned to see if there are any trans codes. If there is no light, it could be the trans control module. However, it could be caused by other things such as a bad torque converter, front pump, worn clutch plates.
