overall from my research, rubicon hondamatics issues are rare, especially compared to other automatic transmission issues. when they do go bad, then yes, they cost alot to fix. personally, i wanted an auto for plowing snow, and the rubicon is so smooth and seamless, i don't know how i survived before it!
