Why are the servos in a transmission case so hard?
The pistons have seals that allow pressure to build up between the sealed servo cover and the piston. The shafts for the servos are hardened (very hard!) steel going through a machined aluminum bore in the transmission case (brilliant design!). This gives you a situation of a very hard metal, rubbing against softer aluminum, so the aluminum wears.
