Question
I have a SearsCraftsman tractor with this transaxle. A problem developed. In forward drive, everything works normal. In reverse,about a month ago, I started hearing a loud grinding noise. And now, when I hit the reverse pedal, it seems to lock up the transaxle and my drive belt is thrown off the pulley. Any idea of how to fix this? Sears is of absolute zero help.

Answer
Have you tried changing the fluid?

This link may be helpful if you need to rebuild the transaxle.

Is the brake assembly causing the noise?  Make sure the transaxle bolts are tight.

Let me know what you find.

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
