Hey JohnC,

Am reading and learning. Thanks for your patience, am somewhat only getting started really getting to know cars and diesels in particular.
3.03 is going to put the engine below its torque peak, understood. I guess my question is still: what rpm would I land up with and how sluggish would that be? Still drivable in everyday driving conditions but just a bit slower acceleration, or almost no acceleration at 65? The fuel economy should be better below torque peak at 65, wouldn't it?

I assume you are saying that the gains in MPG would be too small to justify the compromise in acceleration? Or do I loose mpg because the overdrive wouldn't lock?

Thanks a bunch for your help, I appreciate it.
