I have been thinkin about changing my 3:55s out for something a with a little more oompph, 4:11s seem like a possibility cause my old man has a 02 HO truck with em and that thing will haul *****, in stock trim. Do any of yall have 411s with an auto? if so what kind of milage are you getting? im getting around 17-18 with mostly city driving. does anybody know the over all ratio on a 6 speed 4:11 and the ratios on a auto 3:55 and a auto 4:11?

another quick question, does anybody else with an auto have premature overdrive sensation? lol it seems like mine hits o/d before it needs to.

 

i have a auto and 4.11. i was getting about 14-16mpg with mixed back road and highway

 

If I stay at 60mph or less I can (if I'm mindfull) hit 20mpg-empty. With mixed about 15ish. I do feel that most of my mpg's are from my narrow hwy tires.

The od on mine allways kicks in at 30mph-and converter lockup at 40.

 

With my NV5600 and 4:10's i average about 15-17. My boss has the NV5600 and 3.55's he gets about 18 unless he is towing his 46 foot toy hauler.

 

I have no idea of mileage. Still got a lead foot.
You have to learn to drive using the OD off button. Keep it locked out until 40ish mph.

 

with 285 16's the best i have seen empty driving easy was 19.26 with out correction for tire size hand calcualted

 

I have an extra 2000 dodge with 4.10 which I am thinking of putting in my 98.5 dodge with 3.50 gears and I am running 35in tires. i figure that will bring me back to stock gearing. whats your thoughts ED

I have 275 injectors and edge ez

 

Send me an e-mail to CoastalDav@Bellsouth.net and I'll sent the info you requested on the ratios etc.
