Governor? -2000 Int AmTran

Hi all...just picked up our 2000 Int AmTran and this is the first of what I assure you will be a long list of (potentially) stupid questions.

On the highway on the 500 mile drive home, my new (to me) girl would only do 70 MPH exactly. There was one place where I crested a hill at 70...it was down hill for a couple miles, but she wouldn't do 71. I'm guessing that means there's a governor on her...but I'm so new to this I have no idea where to look or if it's even worth the time given that 70MPH in a skoolie seems to be a pretty good highway speed. Thoughts?

Be glad it even goes that fast.
Its electronically limited or limited by gearing.

65-70 is really all you want to do in a skoolie... for one the wind resistance will make your drivetrain work hard, plus will really lower your MPG's.. there are various threads here about driving at different speeds.. your MPG's will greatly increase by running 60-65 vs 70-75.



the fact it goes 70 with ease even on hills sounds like you got yourself a nice bus!!



but Yes unless you have run out of RPMs.. (most Navistar engines max at 2600-2700 RPM redline).. then the speed limiter is in the computer and can be turned off with a scan tool. if youy are hitting 70 MPH at the above RPM, then youy are running it as fast as its capable of.
