ZF-8HP45/8HP50 P3 Planetary Gear Set

Our used and refurbished P3 Planetary Gear Set is the No. 3 planetary carrier assembly for select ZF 8HP45 and 8HP50 eight-speed automatic transmissions. The carrier holds the pinion gears in position as they mesh with the sun and ring gears. Together, these components transfer torque through the transmission and help produce its gear ratios.

Inspect the P3 assembly during a rebuild for chipped or pitted pinion teeth, rough rotation, excessive pinion play, or wear at the center sleeve. If you find gear damage, check the mating sun and ring gears before installing the replacement.
