i have one question to you, what is the top speed of your freightliner? i just rebuilt my transmission allison at 545 4-speed and my truck doesn't go more than 55mph on the freeway with 2500 rpm, i'm thinking probably it has speed limiter in it:argh:
yea stock gov springs in the pump and having a non lockup tq converter severly limits the speed. We also service 2 trucks with dt466 with 4spd non lockup and they are tapped at 60 just before redline
