Before you buy on-line or order one from Calif. do some asking in your area. Call a few speed shops and talk to them. Ask anybody at a car show who does their trans work. I would MUCH rather buy local to have the support readily available and happily pay a "little" more to have that and not pay shipping.
Just a thought, but I have found it much easier to work with someone local on these things and I guarantee you will find someone who will take care of you.
