reverse drum
For one thing, a warped drum might prematurely wear out the band.
Also, they often show significant wear in the middle where the teflon
seals ride. If that area is rough or warped, you will soon lose reverse.
A brand new ACDelco one is $89:

Other vendors sell aftermarket ones for a bit less.
