Check if the sliding surfaces of the discs, plates and flange are
worn or burnt. If necessary, replace them.
HINT:
wIf the lining of the disc is exfoliated or discolored, or
even a part of the printed numbers are defaced, replace
all discs.
wBefore assembling new discs, soak them in ATF for at
least fifteen minutes.
