4th calculator down

 

welp, you learn something new every day, eh? Can't say I've ever owned an automatic in the 11 vehicles I've been through. They're still foreign to me. Sorry I can't help ya.

Neon, you know you can just jack up your rear end and find out your gears, right? Given your revs, I'd say you are either 4.10s or 4.56s, but I really haven't had my 4.56's up to 70 yet as I'm still in the early stages of breaking them in.

 

What would be some good gearing for a 2wd? I just want to increase MPG and maybe get a jump off the line.

got a 1996 360 5.9L 2wd.

 

The NV3500 is .73 in 5th gear

 

Probably going to be one or the other bud, not both. Higher gears = more off the line, but poor gas mileage. Lower gears = better MPG, but worse take off.

Some here have experienced different results, but I believe thats the general rule of thumb.

 

I just purchased my truck 2 weeks ago. Yesterday I went out to check the gearing by lifting the tires and doin one revolution with the tire. Driveshaft spun 4.5 turns. YES! I have 35 inch tires so I will check and report back when I get the info. I am not sure if the speedo is correct thou. Give me a couple of days.

 

Actually that's *** backwards.

Lower gears = more off the line

Higher gears = better top end

 

I think he was talking Higher as in numericallynot it the ratio aspect

 

Well then for the gears, I guess jump. I can improve MPG through air intake, tune-ups, all that jazz. Is it even worth it though? I only use it as my DD.

 

Does a bear **** in the woods ??
