Lost reverse, need help finding it. 727

Don't remove the servo unless you see visible damage. If nothing is visibly damaged, no servo or low/reverse band damage (broken), then you need to put it back together, fill with fluid, and do pressure tests. If all circuits pressure test within spec, the front clutch pack is smoked.

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.
