Question about 904 tranny kickdown band adjustment

Yes, I blocked the gas pedal full open and checked it. I read one person's reply to another thread on this subject that asserted the kickdown band adjustment could affect shift points. Does anyone know if the adjustment can affect whether or not it will downshift at full throttle? That will help me troubleshoot the issue.
Good. So then the kd lever is all the way back also. The band would really have to be out of adjustment. Kim
