Which basically translates into engine speeds well below 1500 and into the beating the engine to death dropped liners excessive wristpin wear bearing wear etc the slower you go with it. That's why we say get 3.55s and up assuming higher weight is involved.

Thanks. I wonder how long the engine will put up with being lugged at low rpms? Typical trips with grain are 80-90,000 lbs one way, either 20 miles or 80 miles, then back empty. I think the auto shifting can be set to different modes and you can run in manual to keep it in the gear you want.

I've checked with my local shop about demandating and they said it's an option but how do I know if they'll do a good job? What do I need to be able to send the code to be looked at by someone who knows good programming from bad?
