D Z Greenfield , IN November 29, 2014 Appliance: KitchenAid 6 Qt. Stand Mixer KP26M1XPM4 Kitchenaid Mixer Kp26m1xpm4: Had a friend with a kitchen aid mixer that would not run. How to replace Transmission Housing. Being somewhat handy I told I would be glad to take a look and see if there was something I could do. Got the mixer home and found the transmission housing broken and front bearing breaking up also found worm gear assemble chewed up some. Found Appliance Parts Pro online and was able to all the parts needed to make what I am sure will be a long lasting repair. Once unit was cleaned of all the old grease and particles from bearing, new parts and appliance grease was added to complete the repair. Return to my friend in great working order. She was so please she called later in the day to say she had made a big batch of Pumpkin bread, Yum, thanks for your quick shipping and having everything I needed to do this project. From the time I took the mixer, diagnosed and order parts and made the repairs, I had the mixer back to her in 7 days, Thanks again your are definitely in my favorites. 26 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
