Hey guys got a new truck the other day and today I was driving at highway speeds about 65 and the tranny kept jumping out of overdrive and down shifting then it would pop back in after a little bit and sometimes in won't go into OD at all. What could he goin on? Something with valve body? Thanks in advance and its a 94 standard cab

 

mine did that on my ats and it turned out to be my tcc solenoid and that caused a few fins in my tc to weld together

 

My vote is bad TPS

 

Could it have something to do with my kick down cable?
