hey guys, so a friend of mine drives an 02 cummins, its 4x4 auto and the mods he has are the edge comp and a rapter 100.his trans has been slipping really bad lately and he wants to get it rebuilt but him being in highschool, doesnt have that big of a budget. so i was hoping you guys could help me pick the parts out for a rebuild kit for it? he might add 100 injectors later on so at least a tranny that can hold around 450hp

i was thinking
1. red eagle performance rebuild kit
