OASIS Rpt?
I have a few questions regarding info off my OASIS rpt. on my new (used ) truck.
It states I have 3.73 ratio under axle ratio. Are those the tallest gears for a F-350 4x4 ZF-6 spd? That gearing should yield the best fuel milage ...right?
Plus with the 6 spd. they should be fine for hauling a 8ft. S&S self contained slide in camper and pulling a two horse slant?
The axle type is listed as EGJAB-non-limited slip rear axle? Is this the same as what we used to call posi-trac? Can someone explain what it means exactly. And it's a good thing to have....right?
And lastly....under installed options it states Mirror Driver side..Electrchrmc power heat mirror? I'm guessing my drivers side mirror has a defroster? But where do you turn it on? Is it something that's automatic by a temp sensor? Whats electrchrm ...whats that mean?
I bought the truck 1/30/09 and just discovered these items. The dealer didn't even know it had the six speed. It's listed in the window equipment list as a five speed. I just learned I have thse other things a minute ago.

The 3.73 should be fine behind the 6 speed for towing unless you head up in the mountains. Then you may end up having to down shift to keep the rpm's up. I've got 3.73's in my truck with the 6 speed and have towed 20k with it, so the 2 horse slant will be fine.
The non-limited slip is an open differential. No limited slip or posi-trac type action at all.
Don't know about the mirror, but the dealer is an idiot. The only manual they put behind the 7.3 in the 99-03 trucks was the ZF-6. Of course it really is more like a 5 speed with a granny gear, or at least that's how I look at it. You can barely move forward in granny gear, but you can pull 2 houses off their foundation without slipping the clutch with it.

Hook it, I'll pull it.

No problems with the 3.73 and 6 spd. I think Chris said about all that needs to be said. Have fun with it and enjoy. I thought all dually trucks had LS. but I don't know about the 6 spd.
