Its not that the duration of the shift is excessively long but rather the timing of just the 3-4 shift is late and sometimes allows the engine to rev to redline before allowing the shift to occur. The quality of the shifts themselves once they happen are very good quick and firm no flaring slipping or anything like that. I currently have removed the valve body and i am checking for dirt build up and worn parts because the microfiche service manual that i have said that might be an issue. I will let you know how i do. Could the k1 band not be engaging at that giving me this problem as well thanks
