2001 ford f150

2001 ford f150 5.4L 4r70w transmission

Lost reverse and would disengage out of drive on turns and when coming to a stop.

Did a complete overhaul and found the weld had failed on the sun shell gear. That fixed reverse.

It is still disengaging out of drive

Fluid is at correct level and a new torque converter and valve body

Any help is appreciated
