Gearcase (Transmission)
Genuine Whirlpool part
By: Whirlpool
Part Number: 9708070

This gearcase transfers motor power to the wash tub and agitator, restoring normal agitation and spin cycles for top-load washing machines. Replaces a worn or failed transmission assembly to recover wash performance. What it does:

  • Converts motor rotation into the low-speed/high-torque motion needed for agitation and the higher-speed motion for spin
  • Restores normal agitation and spinning when a washer fails to move or completes cycles poorly
  • Reduces grinding, clunking, or slipping noises caused by worn internal gears
  • Helps stop leaks of internal gear lubricant when the seal or housing is compromised
What's included:
  • One gearcase assembly
Install notes:
  • Disconnect power and shut off water before starting; follow the washer service manual for safe disassembly
  • Gearcase replacement may require removal of the inner tub, drive coupler, and mounting hardware—have basic hand tools ready
  • Inspect surrounding seals, gaskets, and mounting bolts; replace any damaged components to prevent leaks

Genuine Whirlpool part
By: Whirlpool
Part Number: WP9709231

Mixer slipping or making loud grinding noises? This worm gear transfers motor power to attachments. Moderate DIY repair with cleaning required.

Do-It-Yourself Stories from Customers like You Stripped worm gear this is the fourth time in 6 years my wife uses this 6 quart mixer a lot!   Philip R. • Wichita , KS • March 06, 2015

This time I replaced the front and rear bearings and thrust bearing and all the gears. The hardest part is thoroughly cleaning out all the old grease. After re-greasing and assembly mixer ran like new. I wish a more robust worm gear was available. A snap ring plier is a must for this job. Read more

Do-It-Yourself Stories from Customers like You 2001 vintage kitchenaid professional 6 mixer suddenly starting knocking badly and then seized up   Richard R. • Honolulu , HI • April 01, 2017

Opened up transmission housing and removed all gearing to inspect for worn parts. The Professional 6 is all metal (except for the transmission housing cover) so just a couple of gears looked worn. Planetary needed adjustment, although the gearing was solid. Replaced the transmission housing cover with a new metal version. Cleaned out the old grease (all that grease...) and repacked the gears. Closed it up, ran it for 30 minutes to set in the new grease, and everything sounds smooth and... Read more

By: Whirlpool
Part Number: WP9708175

Planetary gear assembly for KitchenAid stand mixers. Installs on the drive shaft to rotate beaters. Replace if bent, cracked, or teeth are worn.

Do-It-Yourself Stories from Customers like You After replacing most gears in kitchenaid pro 600 and mixing two batches of whole wheat bread the mixer again had some gear grinding noises   Vern Z. • Carrollton , GA • August 11, 2014

The vertical shaft showed a slight bend so I replaced the bent shaft with a new shaft. I should have done that when I was replacing the gears. Although we have not mixed any more bread, I ran the mixer at a both low and high speeds for several minutes without any more gear clashing noises. It now purrs ! The top bearing on the original vertical shaft had slipped down the shaft when I first examined it. This may have been the source of all of my problems with this mixer. It may have been... Read more

Do-It-Yourself Stories from Customers like You Motor not turning   Dolores M. • Queen Creek , AZ • February 14, 2025

DID A FULL OVERHAUL on the KitchenAid Stand Mixer. I've had the mixer for over 25+ years and it finally stopped working. But instead of buying a new one, which is not made the same, I did an almost complete overhaul on this one. Replaced: Lower Gearcase, Transmission housing, front sleeve bearing, worm gear, motor shaft seal, worm follower gear, and drive motor. Watching the videos was very helpful, especially when removing the lower gearcase. Read more
