The problem with that is that for a person that has never seen or dealt with it before probably won't be able to tell if there is servo damage.
Some just crack around the lip edge and is hard to see until it's out.

No junk in the pan and no bad smell or color to the fluid, I would soooo be pulling that servo and inspecting it.

Yes, there is no junk in the pan, no burnt smell, and fluid looks normal.
I figure it might have something to do with the servo, but figured I would ask.
I will pull that out next, and check for cracks.

On another note, the car runs 11.83 @ 113. People have said the tranny is probably slipping , say the mph is low for the 6500 trap speed.
440, 4000 stall converter, 4:11 spool, 27.8" , tall tire.
