After the torque converter is removed place the transmission into a holder or stand 

it up in a drain pan on floor. Place transmission with bell housing down. Remove 

the rear extension housing as an assembly.  Remove park pawl pin, park pawl, C5 

return spring assembly.  Remove P3 sun gear and thrust bearing.

NOTE:

  Pay  attention  to  the  directional  install  of  Torrington  bearing.  Inverting 

bearings will result in Extreme Damage.

Grasp  the  main  shaft  splines  and  lift  straight  up  to  remove  the  main  shaft,  P2 

sun gear and spacer.  Remove P2 planet carrier and thrust bearing.  Remove C5 

clutch pack and backing plate.  Remove P1 planet carrier assembly and thrust 

bearing. By lifting up with a slight twisting motion leaves the P1 ring gear in place.

We recommend performing all C4 clutch modifications first.
