Get a replacement cable, part number should be in your user manual...when you get the cable it should have directions on how to replace.

I fixed the drive cable just yesterday. If the model is exactly hrx217hxa with the serial number between MAGA–1000001 and 139999 as mine is, it can be quite involved to replace the cable if this is the first time, because honda wants to replace the "control arm" as well. You can find a detailed instruction to replace the drive cable from the following link.

The part number that you need to order is 06225-VH7-305, which comes with a very brief instruction on how to replace based on the service manual (not the user manual). The above link will guide you to how to replace the cable, but since the transmission end of the cable changed, you need to replace the "control arm" as well. This requires to disengage the drive "belt", which is the first challenge. Once you disengage it, it is relatively straight forward to replace the "control arm" if you have the right tools (1/8" pin punch and a challen lock plier which are described in the instruction that came with the cable kit).
Engaging the drive belt back on is the biggest challenge in the whole process, unless you have the right tool to handle the powerful spring that pulls the whole transmission to give friction to the drive belt. I spent two hours to try to engage the belt without the right tool (probably you need a "brake spring tool"), and I finally did it.
The rest of the assembly process is straight forward if you memorize what you did for disassembly. The above link can help you as well.
I took pictures of every step, and am going to post it somewhere soon, but if you want to replace it soon, please send me a message if you need help.
