I was wondering what the ideal running temperature is, oil pressure, and RPM's in overdrive. If anyone could help me out with these it would be greatly appreciated.

running temps: 180-200, they vary considerable due to thermostat setting, cooling system health, fan clutch setting, etc


Oil pressure: I would want 30-40 hot running or higher. Idle hot could be a little lower. Factory gauges are not exactly accurate though.


RPMs in OD: depends on your: differential ratio, tire size, speed, if your lockup convertor is working, etc, for instance: with 3.42 diff ratio, at 75 miles per hour, with 30 inch tires, and an overdrive ratio or 70% ( and a locked up torque convertor) you will be turning 2011 RPM. Get the specs on your truck and go to www.4lo.com (http://www.4lo.com) to calculate. Edited by: azblazor

Thanks for the info
