4.10 gears on the highway?

jrfan4life · March 8th, 2007, 04:43 AM

Ok.....So from everything I read, With a 2001 gt with an automatic tranny I should run 4.10 grears for best launch. My worry is what about on the highway? Right now at 70mph I am at 2100rpm. How much will this increase with 4.10gears? I drive the highway almost everyday for about 10 miles.

For just 10 miles on the highway you shouldn't be worried. I'm just guessing here cause I don't drive an auto, but 4.10's should put you somewhere around 2,500-2,700 at 70ish. Hell with an auto you could go even to a 4.30 and not have to worry about highway driving.

Don't guess, use this.

Timber....
I dont see the auto tranny in the list?

Timber · March 8th, 2007, 07:14 AM

4R70W is an auto, but I'm not sure if that's the one in you car or whether it's std or wide. Google your car and year or the tranny to find out exactly what you have.

Or find out the overdrive ratio in your car and use this one.

That's the exact same position I'm in. Mine is a '01 Bullitt and I doubt I'll ever do the track thing. I just wantsome get-up-and-go. I'm leaning toward 3.73 but not sure if I was 4.10. I don't ever see a SC in my future for this car.

jrfan4life · March 8th, 2007, 10:21 AM

I am just worried ablut every day driving... but i dont wana do 3.73 and not even feel a diferance and get pissed at my self for not doing 4.10. Thats why i was looking into 4.10....

Timber · March 8th, 2007, 10:42 AM

If you're going from 3.27 to 3.73 you will feel a difference, it's when you only go up one gear like from 3.55 to 3.73 it may be hard to tell.

jrfan4life · March 8th, 2007, 10:50 AM

Have you decided what you are going to do yet?

jrfan4life · March 8th, 2007, 11:38 AM

Ok....well Im going to go with the Motive 4.10 from RPM outlet.... now I should probably buy the bearing package with it for 70.00 right.... The car has 70,000 on her.... I must say RPM OUTLET has everything!!!!!!!
