(71) Check clutch and brake operation. Operate
clutches and brakes with compressed air applied
through feed holes in case (Fig. 56). Listen for clutch
and brake application. If you do not hear a clutch or
brake apply, disassemble transmission and repair
fault before proceeding.It is necessary to block
the overdrive clutch accumulator feed hole No.
