WP8577376 - Genuine OEM Whirlpool Washer Transmission Shaft Seal

The WP8577376 Genuine OEM Whirlpool Washer Transmission Shaft Seal is a factory-certified replacement component designed for Whirlpool washing machines.

Available from Appliance Kingdom, this part ships quickly across Canada, making it a dependable solution for homeowners, landlords, and appliance repair professionals.

This part is commonly used to resolve water leakage and internal wear issues, helping restore your washer’s performance and extend its lifespan.

Function & Importance of the Transmission Shaft Seal

The transmission shaft seal sits around the shaft that connects the washer tub to the transmission (gearcase). Its primary function is to:

• Prevent water from leaking out of the tub

• Protect internal components such as bearings and transmission parts from moisture damage

• Maintain proper washer performance and longevity

Because this seal is constantly exposed to water, pressure, and rotational movement, it naturally wears down over time. A genuine OEM seal like WP8577376 ensures the proper material strength and fit needed to withstand these conditions.

Common Symptoms of a Faulty Shaft Seal

If your washer is showing any of the following issues, replacing the transmission shaft seal is often necessary:

• Water leaking from the bottom of the washer

• Puddles forming underneath the machine after cycles

• Unusual noise during spin cycles (due to water-damaged bearings)

• Signs of rust or corrosion near the shaft or tub area

• Washer experiencing shaking or performance issues

Will replacing this part fix your issue?
If the leak originates from the centre underside of the washer or near the transmission shaft, replacing this seal is a common and effective repair.
