estimated RPM's?

[exindust]

I got a 2000 Auto v6

With 3.73's what is the Estimated RPMS...
at 45 MPH
at 70 MPH (or typical freeway speed)

With 4.10's what is the Estimated RPMS...
at 45 MPH
at 70 MPH (or typical freeway speed)

in an Auto with 3.73's or 4.10's is the car going to be able to keep up with the shifting as the rpms will max faster? I dont wanna redline and blow it.

I don't know the information that you asked for. . But your car won't blow up. Mustangs aren't that wimpy. Maybe with a 200 shot of Nitrous on stock internals, but not with just gears. From what i heard too, which i'm sure you have too, 4.10's is the only way to go with an automatic.

no need to estimate RPM calculator Ignore the GM stuff at the top. You need to find out what each of your gear ratios are, Here . I don't know which Auto they use, I'm a manual guy

The tranmission is told when to shift based on engine conditions, besides that the computer doesn't allow the engine to spin to fast. All modern cars have elctronic rev limiters

Here's the stock gear ratio's to help you out some.

Gear ratios------V6 Manual----V6/GT Automatic------GT Manual
1st--------------3.35:1-----------2.84:1------------3.37:1
2nd--------------1.99:1----------1.55:1------------1.99:1
3rd--------------1.33:1-----------1.00:1------------1.33:1
4th--------------1.00:1-----------0.70:1------------1.00:1
5th -------------0.68:1------------none--------------0.67:1

Here he comes to save the day!!!

v6 auto with 4.10s at 45 is like 1900 rpms.

v6 auto with 4.10s at 70 is like 2700 rpms.
