i just had my trans rebuilt by dtt and all i can say is WOW this trans is awsome. i also had 3k gsk put in. i put the 370's in about a week before i had the trans done. when i got my truck back it is a whole different truck. the stock trans held up for the week but the dtt trans lets me use all the power the truck. this trans is simple awsome. just wanted to let everyone know how it is with all this new found powerOo.
