Welcome, I'm pretty new as we'll to this forum... Kinda disappointing someone didn't at least welcome you to the forum... If you still need help, let me know. I'm somewhat local and can help.

Welcom, rmillen!
I wish I could help you with a reputable shop in the PS area. Heading west to OC will certainly open your options (Voss Performance, V's Performance)
Tell us about your Kirkham.
Sometimes the clip can come off that holds the cable in place where it plugs in to the back of the transmission. This can cause the cable to back out and disengage. Could just be a matter of pushing the cable back all the way in and reclipping it to hold it in place. This happened on my Cobra replica, took 5 minutes to fix. Just an FYI if you wanted to check it yourself. Cheers and welcome to the madness.
