Jerry L Earlville , IL April 10, 2017 Appliance: Maytag Washer MVWC400XW3 Maytag Washer Mvwc400xw3: Never checked the codes just listened to others stories. How to replace Washer Shift Actuator. Did some research on YouTube and AppliancePartsPros.com. Purchased shift actuator from AppliancePartsPros unplugged and laid washer on front I laid on the back of washer reached down took out 2 screws and 2 bolts put it on and it worked like a new machine. I might add that the Little Wife was really really mad at me when she seen how fast the repair was done and that I held off 6 months on fixing it. Didn't have washer a year and had to replace trans as the seal leaked and damaged bearing and I just didn't want to put more money into it 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
