This component is essential for restoring proper agitation and spin performance, making it a common fix for major washer drive system failures.

Function & Importance of the Transmission Assembly

The transmission (gearcase) assembly is the core mechanical system that transfers power from the washer motor to the drum or agitator.

• It drives the agitator during the wash cycle

• It controls basket spin speed during the spin cycle

• It ensures smooth transition between wash, rinse, and spin operations

A properly functioning transmission is crucial for effective cleaning and water extraction. When this component fails, the washer cannot perform its core functions. According to manufacturer-based sources, this assembly directly controls both agitation and spinning operations.

Using a Genuine OEM transmission like W11449840 ensures proper torque, durability, and alignment—critical for preventing further internal damage.

Common Symptoms of a Faulty Transmission Assembly

If your washer is showing any of the following issues, replacing the transmission assembly may resolve the problem:

• Washer won’t spin or spins weakly

• Washer won’t agitate or clean clothes properly

• Loud grinding, roaring, or knocking noises during spin

• Washer pumps water but does not spin

• Oil leakage from underneath the washer

• Clothes come out soaking wet after cycle

Will replacing this part fix your issue?
If your washer motor runs but the drum does not move correctly—or if you hear loud internal mechanical noises—the transmission assembly is a likely cause.
