Dday uses his deep pan, BRS valve with quick release transbrake set up on his tranny. This guy is a West Coast NHRA Comp Eliminator/Super Stock word champion which he engineers all kind of billet parts for the 2004R transmission which many different classes of NHRA racers use in their race cars. Like Grumpy stated- he has been around for a long time and can build a 2004R tranny that can withstand a lot of power.
