About a month ago the trans fault light came on. i pulled the code and it was a p070something. i had no clue what to do and autozone (bad idea) said to replace the tcc solenoid, after an hour and a half job of replacing that, trans fault back on. I researched it more and concluded it could be the trans range sensor. the rpms jump from 1100 to 1300 while going 20-30 mph constantly, and shutters while accelerating and decelerating, am i correct on the part???
