What do you think about 3.73 gears on an auto?

[ONEbadmachONE]

Hey guys, thinking about going with some 3.73 gears but I have an auto in my mach. Some people advise against it some say its crazy awesome! What do you all think? Also I have heard the gears are easy to swap in a mach. Anybody have any experiance doing them?

Go with a 4:10

3.55 to 3.73 would really not be worth the money. I strongly suggest the 4.10.

Why just go up less then a .2 and with an auto... Get the 4.10's...

I agree! 4.10's and no looking back!

If it was mine, I'd put in at least 4.10s. I have a 5 speed though, so after driving with 3.55s, I swapped up to 4.30s. I don't know what the overdrive ratio is in an automatic Mach1, but I'm sure that 4.10s would really wake it up. Gears are the best "bang for the buck" mod that I've tried yet, plus you'll really improve driveability with 4.10s. :burnout:

3.73 are good on a 4 spd car. youll see a big difference off the line with minimal wheel hop increase. going with 4.10's on stock suspension is a waste of cash. whatever gain you might have picked up with be lost because youll have to feather it out of the hole to prevent wheel hop.

4.10s rob more rwhp that 3.73s too.

just my .02

Thing is I just dont want it to start humming on the freeway/ using up craploads of gas. I guess you have tradeoffs for more acceleration. Hey thanks to all of you for your input! Sounds like 4.10's it is. //)

correct me if im wrong, but i think you can get a 3.90 gear. it still would not be much different then the 3.55s, but it would be better then 3.73, and plus it would be something different. but 4.10 is still the way to go :rockon:

 

[Mr. Mach-ete]

forget the 3.73 go with the 4.10s.

 

[Hot02ss]

4.10s are gonna suck down more gas on an auto tranny.

Some say the swap is no sweat,...but it isnt a 9 inch so i'd say assume its not easy. All these procedures are tougher than expected first time around.
A couple people here have the gears so hopefully they will give you an actual heads up.

4:30's. Won't regret it. Not much of a cruisin change between the 410's and the 430's.

you will barely notice a decrease in gas mileage if you notice one at all. i know alot of people that switched to 4:30 and still get 23 MPG on the highway

you'll lose 2mpg on the freeway. on a 14 gallon tank, that's 28 miles, roughly another gallon and a half worth of gas. that's ~4 bucks more in gas per tank that you'll be missing... at 4 bucks per week - or however often you fill up, you won't feel it... trust me.

Go with the 4.10s, you won't regret it

I get about that on the highway, and my mileage went up in the city, b/c i can now use 5th around town, 1500rpm at 45mph...

4:10's or 4:30's....I'm a sick puppy so I would have 4:30's in my auto. Definetly upgrade to 31 spline's............
