last night on the way home from work I tried to narrow it down a little,
in 4th it keeps going from 1500 rpm to 3500 back and forth this is at about 40 mph , when it was at the higher rpm I downshifted 3rd and there was no change in rpm . I also tried this at 60 mph low rpm was 2500 and close to 4000 when it kept downshifting. I also downshifted at this speed and there was no change in 3rd at the higher rpm. So for some reason it's going into passing gear or 3rd . I also believe it's a sensor or TCI but finding out which one will be tough. Thanks for all the help you guys
