Joe at Transact of Indy. No Core Charge. He built me a stout transmission to go behind my Twin Turbo Motor. I just got it about 1 week or so ago. Pro Billet Transbrake, billet front drum Race Clutches and all the go fast goodies. He puts the transmission on his trans dyno before shipment and puts it through its paces and adjusts everything making sure it is good to go before he ships it out.
