Thanks for getting back with us David!

Thing is a good number of people on the forum have had the P0705 DTC and almost all ended up replacing the SLA. That isn't a hard job. You can do it yourself, just watch a video and go slow.
Here is a link with several videos it should be helpful. Read the entire thread but the videos are at post #9 P0705 repair
Your best bet for a used SLA will be on ebay. They are all the same Limited or SRT6.
Good Luck.
