Can a speed sensor cause weird shifts?

[Highridge]

A quick question,
I know my speed sensor is going out because the speedo needle wiggles and bounces, but today after i was doing about 75 on the highway for 45 mins and i got off and went to accelerate and noticed the engine was reving a lot higher than usual to shift for a few miles then it went back to normal. Could it be the sensor or is it the sign of a more serious problem?

Thanks

Yes it will and can also help trans failure along the way sensor are cheap about 28 bucks my cost for ford sensors replace it and test drive they go out all the timel

make sure the fipl is good to, that causes bad shitfs also, I just did mine, and it cleaned it up. Cheap insurance, and they only last about 60k miles.
