Thanks for feedback. I was aware of the K72 but I noticed on blogs that sometimes you have to change other parts or brackets. Would the K66 or K72 be installable on the JD x340 without other modifications. I would really like to install a transmission that is going to be able to handle the functions I purchased the X340 for and at a cost of $5000 I would like it to last as long as possible. I thoroughly maintain this mower for that reason, and purposely did not buy the box store version. Had I known about the K58 weakness in the X340 I probably would have gone to the X500 version 6 years ago when I could afford it. I'm retired now and can't do that so I need to repair this tractor with a transmission that will last.
Use the K66 for your new transmission. The K72 will require too many alterations/modifications of your tractor to be a practical swap. A K66 will be much easier to install, and should do the work you need with no problems.
