wheel speed sensor on 1995 GMC Yukon

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
would my wheel speed sensor cause my transmission to down shift if the speedometer is readin 50 then drops down to 30, or would that be something else?

In my car I was having the same problem until I changed the speed sensor that was on the transmission.
