2. Remove two crossmember to frame attaching bolts, then raise transmission enough to remove weight from crossmember and remove crossmember.
3. Disconnect muffler inlet pipe from exhaust manifolds and let pipe hang.
4. Place drain pan under servo and remove servo cover to transmission case attaching bolts.
5. Remove servo cover, piston, spring, and gasket from case, turning band adjusting screw inward as piston is removed. This ensures there will be
