45. Reinstall the agitator cap (if present) by snapping it into place.
46. Reinstall the top panel by aligning it with the washer and securing all fasteners along the back edge.
47. Restore the water supply by opening the supply valves.
48. Plug the washer back in and restore power.
49. Run a test cycle (without clothes) on a full wash cycle to verify proper transmission operation.
50. Verify the washer fills with water during the test cycle. Water should flow into the tub within 10-15 seconds.
51. Verify the agitator moves during the wash phase. The agitator should move back and forth smoothly (approximately 180-degree oscillation) without unusual noises or binding.
52. Listen for the transmission shifting from agitate to spin mode. You should hear a brief clicking or mechanical sound as the transmission shifts.
53. Verify the washer drains at the end of the wash cycle. Water should drain within 1-2 minutes.
54. Verify the basket spins during the spin cycle. The basket should rotate at high speed without unusual vibrations or noises.
55. Listen for grinding, squealing, or clunking noises during the entire cycle. The transmission should operate quietly with only normal mechanical sounds.
56. Monitor for oil or grease leaks throughout the test cycle. Check the floor around the washer and the bottom of the washer cabinet for any leakage.
57. If the agitator does not move during wash, verify the transmission is properly mounted and the agitator is properly seated on the shaft. The transmission may not be engaging properly.
58. If the basket does not spin, verify the transmission is shifting to spin mode and the clutch is engaging. Listen for any unusual noises during the transition from wash to spin.
59. If grinding or squealing noises occur, the transmission may not be properly seated, the motor coupling may be misaligned, or internal components may be damaged. Stop the cycle and verify all mounting and connections.
60. If oil or grease leaks, verify all transmission seals are intact and the transmission housing is not cracked. A leaking transmission may need replacement.
61. If the washer stops mid-cycle, verify the control board is functioning properly and sending proper signals to the transmission and motor.
62. If the transmission does not shift between modes, verify all electrical connections are secure, especially the shift solenoid connector (if equipped).
63. Run a full wash cycle with a typical load of clothes to confirm the repair is complete and the washer operates normally.
64. 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 very heavy (45-65 lbs)—use proper lifting techniques, get assistance, or use 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 the basket is properly secured to the transmission shaft before operating the washer. This is a major repair requiring significant mechanical skill and specialized tools—if you're uncomfortable with the process, consult a professional technician.

Always verify the motor and clutch are functioning before replacing the transmission. A faulty motor or worn clutch can cause symptoms that mimic transmission failure—no agitation, no spinning, or slow rotation. Before replacing the transmission, verify the motor is running during wash and spin cycles and the clutch is engaging properly. If the motor or clutch is faulty, replace those components instead of the transmission.

Test the motor coupling for wear. The motor couples to the transmission through a rubber or plastic coupling that can wear out or break. A broken coupling prevents power transfer to the transmission. Inspect the coupling carefully and replace if damaged. A worn coupling can cause slipping and slow agitation or spinning.

Inspect the transmission seals for leaks. Water intrusion is a common cause of transmission failure. Inspect all transmission seals carefully for leaks before and after installation. Any leaks must be addressed immediately to prevent water damage to the new transmission. A leaking transmission will fail prematurely.

Verify proper transmission orientation during installation. The transmission must be installed in the correct orientation for the agitator and basket to function properly. Compare the new transmission position to your photos to ensure correct orientation. Incorrect orientation can prevent proper agitation or spinning.

This transmission assembly is model-specific. The W11454738 is designed for specific Whirlpool and affiliated brand top-load washers. Always verify your washer model number matches one of the compatible models before ordering. Using an incorrect transmission can result in non-fit or improper washer operation.This is a complete transmission assembly. The W11454738 includes the transmission housing, gears, bearings, clutch mechanism, seals, and internal components. All components are pre-assembled and ready for installation. You cannot replace individual components—the entire assembly must be replaced if any part fails.

Transmission replacement is a major repair. This repair requires significant mechanical skill, specialized tools (such as socket sets, torque wrench, breaker bar, spanner wrench), and extensive knowledge of washer mechanics. If you're uncomfortable with the process, consult a professional technician. Improper installation can cause poor performance, leaks, or damage to other washer components.

Monitor the first few wash cycles after installation. After installing the new transmission, run several wash cycles and monitor for proper agitation, proper spinning, unusual noises, vibration, and oil leaks. Address any issues immediately before they affect washing performance or indicate improper installation.Transmission failure can have multiple causes. If the new transmission doesn't solve the problem, the issue may be with the motor, clutch, control board, shift solenoid, or another component. Further diagnosis may be required to identify the root cause.

Keep the transmission dry. Water intrusion is a primary cause of transmission failure. Ensure the washer cabinet is dry and there are no active leaks before installing the new transmission. Regularly inspect the transmission area for signs of water damage or corrosion.This repair requires professional-grade tools. Transmission installation requires a socket set, breaker bar, torque wrench, and possibly a spanner wrench. Improper torque on the basket nut can cause the basket to loosen or the transmission to shift during operation. If you don't have the proper tools, consult a professional technician.

Transmission oil should not be added unless necessary. Most new transmissions come pre-lubricated from the factory. Do not add oil unless the transmission is leaking or the installation instructions specifically require it. Overfilling can cause leaks and poor performance.

If multiple transmissions fail prematurely, check for root causes. If the transmission fails again shortly after replacement, there may be an underlying problem causing premature failure. Common causes include water leaks, motor coupling failure, control board malfunction, or overloading. Identify and fix the root cause to prevent repeated transmission failure.

Verify the shift solenoid is functioning (if equipped). Some modern transmissions use an electronic shift solenoid to switch between agitate and spin modes. If the transmission doesn't shift properly, verify the shift solenoid connector is fully seated and the solenoid is receiving power from the control board. Test with a multimeter if necessary.

Check the basket drive block for wear. The basket drive block connects the basket to the transmission shaft. A worn drive block can cause slipping or poor spin performance. Inspect the drive block carefully and replace if worn or damaged.
