Not in Miami it's not. I can get a whole 'nother tranny for $600 in perfect working order installed. Keep asking around, you'll find the price you are looking for.
My dad's buddy on NW 119 St., no longer, if I'm not mistaken, stopped doing regular repairs and has stuck to "exporting," or else I would've referred you. But keep looking around, all round NW 79 St., or poking around Hialeah would be your best bet.
