      👁️

      🔧 Step 1: Inspect for oil dripping

      1. Unplug the washer’s power cord from the wall outlet to eliminate electrical hazards during inspection.
      2. Pull the washer forward approximately 24 inches from the wall to create access space behind and underneath the unit.
      3. Place a work light or flashlight on the floor, positioned to illuminate the underside of the washer cabinet.
      4. Kneel or lie on your back and look underneath the washer at the transmission area, which is the large cylindrical component located in the center of the unit, approximately 8-10 inches above the floor.
      5. Examine the bottom of the transmission housing for fresh oil accumulation – this appears as dark amber or brown liquid, distinct from water which would be clear.
      6. Check the floor directly beneath the transmission for oil puddles or wet spots that feel slippery and have an oily texture when rubbed between your fingers.
      7. Inspect the vertical drive shaft extending from the motor (rear of unit) to the transmission (center) – look for oil streaking down this shaft or oil droplets forming at connection points.
      8. Move to the rear of the washer and examine the motor mounting area, located 4-6 inches from the bottom and centered horizontally – look for oil accumulation on the motor housing or mounting bracket.
      9. Check the rubber transmission boot (black accordion-style seal surrounding the agitator shaft where it enters the top of the transmission) for oil seepage by running your finger along the underside – oil presence here indicates an upper seal failure.
      10. Place a large piece of white cardboard (minimum 18×18 inches) directly under the transmission and let the washer sit for 2-4 hours to detect slow leaks that may not be immediately visible.

      🛠️ Step 2: Remove transmission

      1. Unplug the washer from the electrical outlet and turn off both hot and cold water supply valves completely.
      2. Pull the washer away from the wall to access the rear panel, leaving approximately 3 feet of working space.
      3. Locate the four 5/16-inch hex-head bolts securing the transmission to the mounting bracket – two on the left side and two on the right side of the transmission housing.
      4. Use a 5/16-inch socket wrench with a 6-inch extension to remove all four mounting bolts, turning counterclockwise. Set bolts aside.
      5. Identify the drive motor coupling located at the bottom of the transmission – this is a white or gray rubber coupling approximately 2 inches in diameter connecting the motor shaft to the transmission input shaft.
      6. Grasp the transmission housing firmly with both hands and pull straight up with steady pressure approximately 2-3 inches until the transmission input shaft separates from the motor coupling below.
      7. Tilt the transmission forward approximately 30 degrees while continuing to lift upward to clear the mounting bracket at the rear.
      8. Locate the agitator drive shaft protruding from the top of the transmission – this is a splined metal shaft approximately 1 inch in diameter extending upward through the tub.
      9. Guide the transmission assembly backward and downward, threading the agitator drive shaft out through the bottom of the tub opening. You may need to rotate the transmission slightly (10-15 degrees) to align properly.
      10. Once the drive shaft clears the tub completely, lift the transmission out of the cabinet and set it on a clean work surface.
      11. Verify the transmission is fully removed by checking the mounting bracket is empty and no components remain attached to the motor coupling below.

      ⚙️ Step 3: Replace seal

      1. Locate the old tub seal (part number W10111435) sitting in the groove around the outer tub perimeter, approximately 2 inches below the top rim of the outer tub assembly.
      2. Grip the old seal at any point along its circumference and pull upward with steady force to remove it from the retaining groove.
      3. Work your way around the entire tub circumference, lifting the seal completely out – the seal is approximately 28 inches in diameter and will come out as one continuous rubber ring.
      4. Use a clean lint-free cloth with warm water to wipe the entire seal groove, removing any soap residue, lint, or calcium deposits.
      5. Run your finger around the groove to verify it’s completely clean and dry – you should feel smooth plastic with no bumps or debris.
      6. Take the new tub seal and locate the small molded alignment tab on one section of the seal.
      7. Position this alignment tab at the 6 o’clock position (directly facing the front of the washer) in the groove.
      8. Press the seal into the groove at the alignment tab location, pushing down firmly until it seats completely – you’ll feel it snap into place.
      9. Working clockwise from the alignment tab, use both thumbs to press the seal down into the groove in 3-inch sections, ensuring the inner lip of the seal faces toward the center of the tub.
      10. Continue around the entire circumference, maintaining constant downward pressure as you work.
      11. Once you reach the starting point, press the final section down to complete the installation.
      12. Run your finger completely around the installed seal to verify it sits uniformly in the groove with no raised sections, twists, or gaps – the seal surface should be level all the way around.
      13. Push down on 8 evenly-spaced points around the seal perimeter to confirm full seating in the groove.

      🔩 Step 4: Reinstall transmission

      1. Position the transmission assembly directly below the tub opening, aligning the three mounting studs (located at 120-degree intervals around the transmission top) with their corresponding holes in the tub base.
      2. Lift the transmission straight up until the rubber boot at the top seats flush against the underside of the tub – you’ll feel resistance when the boot compresses approximately 1/4 inch.
      3. Thread three 1/2-inch hex nuts onto the mounting studs by hand, turning each 3-4 rotations before moving to the next to ensure even seating.
      4. Use a 1/2-inch socket wrench to tighten the three mounting nuts in a star pattern, achieving 25-30 ft-lbs of torque with a torque wrench (or firmly snug if working without a torque wrench).
      5. Reconnect the white 6-wire connector to the transmission motor by pushing it onto the terminal block located on the right side of the motor housing – it clicks audibly when fully seated.
      6. Reattach the green ground wire to the grounding screw on the transmission housing’s left side using a 5/16-inch nut driver.
      7. Slide the drive belt back onto the motor pulley (bottom) and transmission pulley (top), ensuring it sits centered in both pulley grooves without twists.
      8. Rotate the transmission pulley clockwise one full revolution by hand to verify the belt tracks properly and doesn’t slip off either pulley.
      9. Reconnect the drain hose to the transmission pump outlet (located at the 4 o’clock position when facing the transmission) by pushing it onto the 1-inch diameter spout until it bottoms out, then secure with the spring clamp.
      10. Plug the pressure switch hose onto the brass nipple at the top-center of the transmission – push it on 3/4 inch until you feel it seat against the barb.

      📋 Step 5: Test for leaks

      1. Turn the water supply valve clockwise to the fully open position – you’ll feel resistance when it stops turning after approximately 2-3 full rotations.
      2. Plug the washer’s power cord into the electrical outlet.
      3. Set the washer control dial to the “Normal” wash cycle position.
      4. Press the START button once to begin filling the machine.
      5. Observe the water inlet valve connections at the back of the machine where the fill hoses attach – look for any water droplets or streams forming at the threaded connection points during the first 60 seconds of filling.
      6. Move to the front of the machine and open the washer lid fully.
      7. Watch the water level rise in the tub while examining the area where the outer tub meets the center agitator post – no water should seep from this seal.
      8. Kneel down and place your hand under the rear of the machine, feeling along the bottom panel from left to right – the surface should remain completely dry.
      9. Check the drain hose connection at the back of the machine where it attaches to the pump outlet – run your finger around the hose clamp connection point and verify it’s dry.
      10. Allow the machine to fill for 3 minutes, then press the START button twice to pause the cycle.
      11. Look inside the tub at the water level – it should be approximately 8-10 inches deep with no visible water escaping anywhere on the exterior.
      12. Advance the control dial clockwise to the “Drain/Spin” position.
      13. Press START once and watch the drain hose where it enters your standpipe or laundry sink – water should flow steadily without dripping from the hose connection point.
      14. Once draining completes (approximately 2-3 minutes), press START twice to stop the cycle.
      15. Run your hand along all checked connection points one final time – they should all remain dry, indicating successful leak-free operation.

      💡 Pro Tips

      Take photos as you disassemble components – they’ll be invaluable when putting everything back together. If you encounter resistance or something doesn’t seem right, stop and reassess rather than forcing it.
