Re: 700R4 build thread.
Now you will be looking at the Overrun/Forward piston Return spring assembly.
Compress spring cage, Remove snap ring.
Turn Drum over, Apply air to the 3-4 clutch feed (shown in earlier post).
This will blow the pistons out. Some builders smack the drum against the work bench to remove pistons, Good way to crack this delicate drum.
Remove the inner O-ring from the Input Drum (pic), DO NOT forget to reinstall this O-ring!!! Upon assembly. Thin Green O-ring in the seal kit.
