Mine 3 speed auto shifted hard like that and a new modulator valve cured it.
My 4 speed auto has allways done that,even after havind it flushed,new filter,synthetic fluid etc.I gave up and learned to deal with it.
I loves my 4 door kicks,and think they are the perfect trucklet.plenty of room,good performance,power everything,and since I went to 4 doors my children and girlfriend come along much more frequently.A definite plus!
