No worries, it was just a bit of advice to make sure you get the best help possible.
The P0700 is a generic tans code, that a dealer's StarScan tool will be able to get more information out of. That being said, it can be thrown by the transmission receiving a low-voltage.
The P0501, I believe, is directly related to the wheel-speed sensor. These are relatively cheap and easy to replace.
I would try the orginal suggestion of having the battery tested and/or swapped out with a known good one. As was mentioned earlier, this could be caused by a battery starting to fail.
When was the battery last replaced?
The WK is quite sensitive to failing batteries and it can result in all sorts of issues.
If it was just one issue or the other, I would suspect the individual components, but with both issues coming up at the same time, I would lean towards a common cause (like a low battery voltage).
Hopefully others can add their opinions as well.
Good luck, and let us know how things progress.
