Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Washer does not spin or leaves clothes excessively wet
• Washer does not agitate or agitates inconsistently
• Grinding, roaring, rattling, or clunking noise, especially during spin
• Water or oil leakage from the center/bottom area of the washer
• Excessive vibration or a loose-feeling spin basket

Check Before Replacing

• Unplug the washer before inspection or service.
• Confirm that the washer powers on and that the motor or drive system is operating before attributing a no-spin or no-agitate condition to the gearcase.
• Run the washer’s manufacturer-specified diagnostic or test cycle, if available, and observe whether the agitator and basket move normally; do not bypass safety switches.
• With the washer empty and powered off, gently rotate the basket by hand and note unusual grinding, roughness, or excessive looseness. This check is not conclusive by itself.
• Inspect beneath and around the center of the washer for signs of water or oil leakage, while avoiding contact with moving parts or electrical components.
• Before condemning the gearcase, check for simpler external drive problems such as a displaced or damaged belt where the specific washer design uses one.

Pro Tip

Part Details

Key Features

• Genuine Whirlpool OEM gearcase/transmission assembly
• Designed for select Whirlpool-platform top-load washers
• Drives both the wash agitator and spin basket
• Includes integrated gearcase bearings and seals according to Whirlpool-parts retailer descriptions
• Also identified as a VMAX 2.0 drive PSC service assembly in the archived part identity

Installation Notes

• Disconnect electrical power before beginning installation.
• Verify the complete washer model number against the part before disassembly; W11449840 is limited to compatible top-load washer applications.
• Because the gearcase is located beneath the wash basket and is part of the drive system, replacement requires washer disassembly; follow the model-specific service procedure rather than improvising.
• Inspect the mating tub-seal area and surrounding drive components during replacement, particularly if the original failure involved leakage.
• After installation, run the washer’s applicable service or test cycle and check for abnormal noise, leakage, agitation, and spin operation.
