A-904 Serviceable?

I don’t see a problem.
It looks like it might have broken a band at some point in its life causing the scrapped up area, but it wont hurt functionality at all.
YAY! Thank You...

I suppose it won't really hurt to try... the car drove "in Drive" before I pulled it out.. it had just been refusing to go into reverse. It went into Neutral and Park ok ... so far as I experimented.
