Hello all. I am a fairly new cummins owner but have always been a fan of the cummins. I recently bought a 05 cummins with 119k. When I bought the truck it was stock with the 48re auto, 4.5" lift on 37x13.5x20. Since purchase I have added a 4" straight pipe, afe stg 2 intake, and a smarty jr. I am wanting to add ii 100hp injectors and the ii bag o parts cp3 pump upgrade. These will most likely be my final upgrades to my rig. I have noticed the tranny starting to slip a little so I need to know the trans mods needed to handle these additional upgrades to make the truck a pleasure to drive and to last. I don't race it but an occasional mustang and ricer beat down is probably going to happen if provoked. Any help with these trans mods would be appreciated.

So would the M3ga 3 rebuild kit offered by suncoast paired with their triple disc converter do the job??

 

That Sun Coast kit and converter should do ok for you.

 

Thank you guys for the help

 

Just make sure the friction material plates are smooth and don't have the grooved waffle looking style that the factory ones do. If I were you I would also bump the line pressure up to reduce the clutch packs slipping.
