transmission shift harsh from second to third around 3,300 rpm's. then will not up shift from third to fourth at all, even at 3,300 rpm's. I have check shift solenoid one to two, and two to three they were both at 21.7ohms. I changed them anyway with new, I also changed the TCC solenoid, I flushed the fluid with new, I changed the filter and gasket. shift was much smoother, but still at 3,300 rpm's. then I heard I should change the throttle position sensor, so I did, and nothing changed. trouble lite have never shown up on dash, code reader shows no codes present. I am about to give up and take to dealer, I thought I could handle this. anyone have any answers?
