I have a 05 superduty with a p-pump 12 valve and smoked the tranny within 2k miles of the conversion. I bought a ats tranny kit and took it to my tranny guy and he said that the only thing different is there is an extra clutch and steel in the foreword drum. The people I bought the kit from said that it would hold up to close to 500 hp. The truck pulls about 15k pounds on a daily basis and about 30k a couple times a month. I need this tranny to hold up so my question is should I put red clutches and or koleen steels in the foreword drum while it's apart? I bought a ats 1650 stall converter and also a transgo tugger kit. I'm pushing around 250 hp.
