Hopefully it is a bad connection to the solenoid. The next thing would be the solenoid, then the TC.

Ok answer this one once I get to second gear either one of the two thing happen
1 either stay in 2 gear and not shift to 3rd or
2 if it shift to 3rd it take an while before actually shifting it will not shift to 3rd until I get like past 60-63 mph

Could having 19" rims be a problem ? But all this just started today well actually I was driving in crusie control at 60 and the CEL didn't come on until hit brake to slow down
