Alright, I had a shift kit and new accumulator (thinks thats what he called it)plate installed on my 03 Dodge cummins. The tranny works great now and shifts quick like I want it too. The problem is, when I am below 35mph and stomp on the gas pedal, the downshifts and red lines and will not shift till I let off the gas pedal just a little bit. If any of you can help me out or have heard about this problem with other guys, write back and give me some tips on fixin this.Its embarrasing when Istomp on it to blow some one away and it wont shift. thanks
