	Incorrect band/clutch application pressures, line pressure high/low	Check line pressure at tap. Carry out line pressure and stall speed tests. Refer to the line pressure chart for specifications. If pressure is high/low, check the following possible component: main control.
Main Control Assembly
	Screw out of torque specification	Tighten to specification.
	Gasket damaged, off location	Inspect and install a new gasket.
	Separator plate damaged	Inspect for damage. Repair as required.
	Wrong components used in rebuild	Verify that correct components were used.
	Dirty or sticking main control valve body	Clean, repair or install a new main control valve body.
Rear One-Way Clutch Assembly
	Low/reverse one-way clutch damaged	Install a new rear one-way clutch and case.
