My car shifts fine most of the time, but when trying to pass on the freeway, it revs, then bangs into third, and if this happens enough it will eventually set the 1811 code, and then all shifts will be harsh. The shift kit helped, it doesn't rev as high or bang as much, but it still does it somewhat. So yeah, I am changing it cause it was listed as the most probable cause for an 1811 code. Should I change the other solenoids while I'm in there. Could the TCC cause the problem I described?
