Shop to fix push-button Torqueflite 727 near Nashville?

Hey all,
I've been trying to find a reliable shop to fix the push-button transmission in my 64 Dart. It won't shift up out of 1st gear. Anyone know a trustworthy shop near Nashville, TN that could do it?

Thanks,
-M.
When you say it won't shift out of first, are you talking about when the drive button is pushed? Will it shift through 1 and 2 manually? Also, have you checked your fluid level? The pushbuttons are fairly simple but there's a few things you could check yourself and potentially save a big bill.
