| THe allison has to relearn to shift everytime you change power levels, poor shift quality is normal for a few miles after switching power levels! On a stock trans, especially a 90 k trans be careful running 4 and 5 as even on a new trans you are playing with fire on the trans!!!
Try driving about 20 easy miles or so with it on level 4/5 befor pounding on it and see if it shifts better!!!
