I've got a 2000 F350 with the 7.3 and a automatic, at 70mph I'm running just below 2400rpm is that about right? It sounds a little high while I'm in the truck but it could be that I'm just not used to driving diesels. Just wondering what everyone else was running.
i dont suppose that Ford would have been kind enough to put a tag on the rearend that tells you what ratio it is would they? Guess I'll go out and take a look
Yes there should be a tag on the rear end passenger side of the differential, this will state the original gear ratio, the tag on the drivers side says synthetic lube....Fred
Just a reminder ... tire diameter comes into the equation ... as well as whether or not the speedometer has been recalibrated for a non-stock tire size.
I have 4.56 gears and 35" tires and I'm right under 2500 @70 MPH
