Is there a scanner that can scan while I’m driving ? I don’t have any codes but I’m having a slight in / out of overdrive from 2000 to 2200 rpm. I replaced the tps. I also get some whining at low speed on start up ? I’d like to drive w a scanner where I can watch live data? Any ideas ?

 

That's the trans dropping in/out of lockup, not O/D. (that would be a much larger drop) Usually, it is indeed the TPS that causes that....... Might want to check the connector at the trans, make sure nothing is screwed up down there. (wires like to pull out of the connector, and short out.)
