well that's good to know hoping the stock trans will hold up untill 100k would be good i think after all the money to spend on delete's i think the trans is gonna have to wait untill starts giving me issues dare ask how much trans build would cost ?

Lol.... It hurts but I'm gna go with a suncoast full competition all billit parts n seems bulletproof for all I got done to mine... I got a buddy that's got his own shop gna get me a new built tranny,put in,h&s overdrive unlock code filters & fluids,everything for $9,500...

yah stock trans it is till shits out , only reason i'm throwing the progammer on is cause of the deletes proabaly be on stock 95% of time and tow mode that be about it cause i dont have the money to do the trans and deletes and my stock trans on my 03 5.9 bone stock lasted untill 120k and has towing life

I'll tell u this if u leave it on stock ull get worse mpg than on performance... U can leave it on performance & stay outa the throttle and be fine... I said the same thing u did til I saw the difference it made... I'm a speed/adrenaline junky n run the balls off my stuff... I take care of em maintenance and looks wise... But I like to let em breath too... I think its amazing what these diesels can do! And this is my 1st & I'm hooked for life...
