Check Before Replacing

• Inspect the drive belt for wear, cracking, or slippage before condemning the transmission
• Check the transmission pulley for damage or looseness
• Inspect the motor clutch and mode shifter — these are common and less expensive causes of the same symptoms
• Verify the speed sensor and motor are functioning correctly
• Check the basket hub and basket connection for damage
• Inspect wiring and electronic controls before replacing mechanical components

Pro Tip

Part Details

Installation Notes

• Unplug the washer
• from the electrical outlet to ensure complete power disconnection.
• Close the water supply valves
• at the wall to prevent water discharge during disassembly.
• Empty the washer
• of any clothes or items inside.
• Remove the front panel
• of the washer by locating and removing the screws that secure it (typically 4-6 screws along the sides or bottom). Disconnect any wire harness connectors attached to the door switch. Carefully pull the front panel away and set it aside.
• Take multiple photos
• of the transmission location, mounting position, and all wire harness and hose connections before disassembly. Document the transmission orientation and any visible components from multiple angles. This is critical for proper reassembly.
• Locate the transmission assembly
• inside the washer cabinet. It's typically mounted at the center bottom of the washer, connected to the motor, drum, and drive components.
• Remove the drum or basket
• by locating and removing the fasteners that secure it to the transmission shaft (typically a large bolt or nut at the center bottom of the drum). Use a socket wrench to remove this fastener. Support the drum as you remove the last fastener to prevent it from falling.
• Carefully lift the drum
• out of the washer and set it aside. Be careful not to damage the drum or surrounding components.
• Disconnect all wire harness connectors
• from the transmission and surrounding components. Label each connector with masking tape to identify its connection point.
• Disconnect all hoses
• connected to the transmission or transmission area (typically drain hose, inlet hoses, or vent hoses). Label each hose connection with masking tape.
• Support the transmission
• with a jack or block to prevent it from falling during removal.
• Remove the mounting bolts
• that secure the transmission to the washer cabinet (typically 3-6 bolts). Support the transmission with your hand or jack as you remove the last bolt.
• Carefully lower the transmission
• out of the washer cabinet. Be careful not to damage hoses, wiring, or surrounding components. The transmission is heavy—use proper lifting techniques.
• Place the old transmission on a clean work surface
• with adequate space for inspection.
• Inspect the old transmission
• for visible damage such as cracked housing, leaking seals, corroded components, broken gears (visible through inspection ports), or water damage. This confirms the diagnosis.
• Inspect all mounting surfaces
• on the washer cabinet for damage, corrosion, or wear. Clean the mounting surfaces with a clean cloth if necessary.
• Inspect all hose connections
• for cracks, leaks, or damage. Replace any damaged hoses before installing the new transmission.
• Inspect all electrical connections
• for corrosion, melted insulation, or damage. Clean corroded connections with a wire brush.
• Unpack the new WW01A00638 transmission assembly kit
• from its packaging. Handle carefully to avoid damaging the transmission or internal components.
• Compare the new transmission to the old one
• to verify the housing shape, mounting hole positions, shaft configuration, and overall appearance match. Ensure you have the correct replacement part.
• Verify all gaskets and seals
• are included in the kit. The kit should include new seals to ensure proper water-tightness.
• Position the new transmission
• in the washer cabinet, aligning the mounting holes with the cabinet holes.
• Verify the transmission is properly oriented
• by comparing it to your photos. The transmission must be positioned exactly as the old one was positioned.
• Secure the transmission
• with the mounting bolts, tightening firmly but not over-tightening (which can crack the transmission housing or strip threads). Tighten bolts in a cross pattern (diagonal) to ensure even pressure.
• Verify the transmission is properly seated
• and does not wobble or shift when gently pushed.
• Reconnect all hoses
• to the transmission, matching the labels you applied earlier. Ensure each hose is fully seated on the connection point. Use hose clamps if necessary to secure connections.
• Verify all hose connections are secure
• by gently tugging on each hose. Hoses should not pull loose.
• Reconnect all wire harness connectors
• to the transmission and surrounding components, matching the labels you applied earlier. Ensure each connector is fully seated and clicks into place.
• Verify all connections are secure
• by gently tugging on each connector. None should pull loose.
• Reinstall the drum or basket
• by aligning it with the transmission shaft and securing the center bolt or nut. Tighten firmly with the appropriate socket wrench.
• Verify the drum rotates freely
• by manually rotating it by hand. The drum should spin smoothly without binding or resistance.
• Reinstall the front panel
• by aligning it with the washer and securing all fasteners. Reconnect any wire harness connectors to the door switch.
• Restore the water supply
• by opening the supply valves.
• Plug the washer back in
• and restore power.
• Run a test cycle
• (without clothes) on a full wash cycle to verify proper transmission operation.
• Verify the washer fills with water
• during the test cycle. Water should flow into the tub within 10-15 seconds.
• Verify the drum rotates
• during the wash phase. The drum should rotate smoothly at low speed without unusual noises or vibrations.
• Verify the washer drains
• at the end of the wash cycle. Water should drain within 1-2 minutes.
• Verify the drum spins
• during the spin cycle. The drum should rotate at high speed without unusual vibrations or noises.
• Listen for grinding, squealing, or squeaking noises
• during the entire cycle. The transmission should operate quietly.
• Monitor for water leaks
• throughout the test cycle. Check the front of the washer, the floor around the washer, and the back of the washer for any water leakage.
• If the drum does not rotate during wash
• , verify the transmission is properly mounted and all connections are secure. The transmission may not be engaging properly.
• If the drum does not spin
• , verify the transmission is shifting to spin mode. Listen for any unusual noises during the transition from wash to spin.
• If grinding or squealing noises occur
• , the transmission may not be properly seated or internal components may be damaged. Stop the cycle and verify the transmission mounting.
• If water leaks
• , verify all hose connections are secure and properly seated. Check for cracks in hoses or transmission housing.
• If the washer stops mid-cycle
• , verify the control board is functioning properly. The control board may not be sending proper signals to the transmission or motor.
• Run a full wash cycle
• with a typical load of clothes to confirm the repair is complete and the washer operates normally.
• Monitor the washer for 24-48 hours
• of normal use to ensure it operates properly without leaks, unusual noises, or performance issues.
• Safety Notes:
• Always unplug the washer before working on it. Close the water supply valves to prevent accidental water discharge. The transmission is heavy—use proper lifting techniques or a jack to support it during removal and installation. Never operate the washer without the transmission installed—this can damage the motor and create safety hazards. Ensure all hoses are properly connected and secured to prevent water leaks. This is a major repair requiring significant mechanical skill—if you're uncomfortable with the process, consult a professional technician.
