    thanks for all of the responses
    i dont drive on the highway much but when i do its usually a long trip traveling to motocross tracks
    wayfast = how was your truck on the highway with overdrive? like what rpm to cruise at 75?
    after what oleshifty said im not sure about 4.56 cause i run my truck hard.
    right now it shifts from 1st-2nd at about 50mph and 2nd-3rd at about 90
    i didnt know you could get 4.30's maybe thats the way to go
