Multiple sensor faults

[Nettie]

Getting service lights for traction control and stabiltack. During the d sa ne time I am getting speedometer gauge jumping and hard shifting on transmission which makes me think speed sensor faulting as well. What could be causing multiple sensors faulting at the same time...

Proper cleaning of throttle body can't hurt,both happen at same time?

Yes it happens at the same time. Every time I make an appt to take it in the errors goes away and the truck acts like nothing ever happens.

How old is the battery?  Check the battery cables and grounds, thrice.  A bad cell in a battery can wreak on the electrical system and send one off in all kinds of false directions.
