700R4 checkball ?
On the 88 and up 700R4s, do you need a checkball in this location? What is the purpose of it?

Gm thought it would soften reverse, but it did not. Sometimes it would get stuck in the capsule & burn the low/reverse clutches. I remove the checkball & leave the capsule in all of my 700R4 & 4L60E units.
