2001 F 350 Down Shift Problems

My F350 will not down shift out of lock up converter when you touch the brake, it will however down shift when you are climbing a grade an push the accelerator but wants to slip momentarily before the trans grabs or the clutches engage.

If you're more than about 10% throttle it won't unlock when you press the brake pedal. It also won't unlock if the brake lights are not working.
