The local dealership. My dad is good friends with the 2 men working in the parts department, and other people there too. And I guess they like my dad a lot, because they've always hooked us up with amazing deals and they're always really nice. Being a dealership is great on it's own, because you know they're going to do it right. Plus, the tranny and work done comes with a 3 year or 36,000 mile warranty.
