loose = more rpms when taking off to achieve a certain speed.

tight = less rpms to achieve said speed (in the same amount of time).

i have a loose 4k and wouldn't want it any other way. i never thought i'd say this, but...i love it being so loose! mmhmm

My 4400 is loose as **** with 2.73s. 4.10s are coming though...I think it is the looseness that ruins the mpg.

i'm sure it does kill city mileage, gears may make up for that, but they will kill your hwy mileage. for me, i drive alot of hwy, so a 3000-3200 stall, higher str, and my 2.73 gears would probably suit me for my purposes untill it breaks, that's all i'm saying. like i said, depends on your goals with the car. thats why i asked the original poster what his goals were.

a stall would hurt your gas milage more than 3.73 gears. deffinatly do the gears before you do a stall.

proper order of mods:

Gears
Lid
LT headers
stall
cam

My SS3600 2.5 didn't affect my mileage. I lost 1mpg from my headers and I need a tune to gain it back. After I did the tranny and converter, my mileage remained the same. I think a lot of the guys on here with low mileage are hurting from driving in slip all the time.

As far as the proper order of mods that debate could go on forever...

no way man, lockup. gears will hurt your mileage more than any other mod if you do highway cruising. stalls should be about the same. i'd be worried more about tranny wear with a stall. it seems that the longest lasting trannys are stock ones

i'm not a fan of messing with internals when your car is a DD like mine

just to let you know, this is not at all the prefered order of upgrades. FIRST lid and catback, then stall, then rest of bolt-ons including headers and y/mid pipes and suspension, and then gears if you want to and have 600 bucks that you dont care about pissing away because if you go this far you may as well buy a 12 bolt, then h/c/intake(pre-2001 guys).

if you guys dont think this is right, look at this thread:

choco, most people that JUST install a converter experience problems due to heat. a properly installed trans cooler and shift kit will probably make your tranny last longer than it would in stock form even with a converter.

I dissagree, the 4L60E is known for having problems when you start adding power. But there are only a few major builders that can make one handle the power and last a long time.

First of all, gears are not the worst economical mod by any means. Second of all, if you do any city driving, then a stall would hurt you more than gears would.
What I would like to know, I'm looking at your sig and everything, where do you actually have experience with any of this? Or are you one of those guys who learns everything they know from Horsepower TV?

And also, just because you are not a fan of something does not make you right.

And yes, the stock 4L60e transmission sucks.

all i was saying was that right now, i'm not in the market for a stall, although i would like one, simply because i can't afford problems with my car as it's my DD. i can't afford downtime at the shop, i can't afford tuning issues, i can't afford...the stall + installation + shift kit

right now i gotta stay mostly stock. stock cars last the longest is what i'm saying, that's all.

never said they were THE worst economical mod. one of the worst though, definitely. most people will see a large drop in mpg with gears than any other mod unless they're all city drivers and never see over 55mph. i get all my information from users and common sense. it doesn't take a genius to know that more rpms = less gas mileage. i know everyone in this world wasn't born with common sense but i take pride in being one of the ones that was and understanding these things.
