How to Fix a Transmission for a Washer That Will Not Agitate

In a top-load washer, the motor creates a rotating motion, and the transmission is what transforms that circular motion into the push-and-pull of the agitator. A faulty transmission causes strange noises during operation and prevents agitation. You can use the information below to help figure out if the transmission is the part causing your washer agitation issues

What is a Transmission? Where is it Located?

On a washing machine, the motor creates a rotating motion, and the transmission is what transforms that circular motion into the push-and-pull of the agitator. The input shaft of the transmission receives power from the motor via a belt, or sometimes directly. The output shaft is what powers the agitator.

How to Tell if the Transmission is Damaged

Does the input shaft on your machine turn? If it does, but the agitator isn’t moving, then the thing between the two of them—the transmission—is the problem.

How to Access and Remove the Transmission

1. Before inspecting your transmission, first ensure that your issue is not stemming from the agitator or any of its components. If you have ruled out the agitator, unplug your washer, remove the cabinet, and locate your transmission.
2. Once you have found the transmission, plug your washing machine back in and run a wash cycle to determine if the transmission is the source of the problem. A faulty transmission makes strange noises during operation. Use caution when performing this step, as the internal components of your washer are exposed.
3. If the transmission is noisy during this test, you need a replacement transmission.
4. Look for signs of oil or grease leaking from the transmission.

How to Install a New Transmission

Rebuilding a transmission isn’t always practical. It is often more practical to replace the complete unit if it is broken. Since the tub seal can be found where the transmission shaft enters the tub, you probably need to get a new tub seal when you buy a new transmission.
