The Ford 5 speed auto!!!
In response to someone asking about 4.33 gears I did some research on ways to get a first gear that equals General Motors 3.06 first gear.The Marauder is at a serious disadvantage with its 2.84 first gear.
Which offers 7.7% less torque multiplication than Chevy's.

Here are the gear ratios for the Ford 5 speed auto that is in the Explorer.

1st = 3.22 a 13.4% difference!!!!
2nd = 2.41 a 55.4% difference!!!!
3rd = 1.55
4th = 1.00
5th = .75

This 1st gear will make the 3.55 gear act like a 4.02 and a 4.10 act like a 4.64!

Check out the 2nd gear difference!!!!

3rd is the same as the Maraduer's 2nd!!!

This would do incredible things to acceleration, since 1st and 2nd gear are close together there would be no falling off the powerband.

I wonder why Ford didn't make this tranny standard in the Marauder?
I wonder how much it will cost to put one in? Since the aviator will have the same engine and transmission a ecm wouldn't be hard to get once production of the Aviator starts.

Is this to good to be true?

Here are the overall gearing numbers:

4speed auto ///////////////////5speed auto
1st 2.84 X 3.55 = 10.08 //// /1st 3.22 X 3.55 =11.43
2nd 1.55 X 3.55 = 5.50 //// 2nd 2.41 X 3.55 = 8.56
3rd 1.00 X 3.55 = 3.55 ////3rd 1.55 X 3.55 = 5.50
4th .70 X 3.55 = 2.49 ///4th 1.00 X 3.55 = 3.55
////////////////////////////5th .75 X 3.55 = 2.66

As you can see the differences are dramatic. Especially 2nd gear.
Highway rpms are ojnly slightly higher and probably won't have an effect on gas mileage.

Who will be the first to make this mod?

The trans's are totally different, the processors are
totally different. The module on the Aviator is a 150
pin module, not even an EEC. That module controls all
kinds of things like the speed control, the climate
control center, and while you may be able to work out
these issues, then the trans is way shorter. The cross
member will have to be moved forward. That trans uses
a flange to bolt the driveshaft too, not a slip yoke.
So, you'll need a whole new driveshaft setup, and make
another crossmember to support a center bearing since
the driveshaft will then need to have the slip part in
it and that requires a center bearing.

It's a lot of work.

So, Maybe it is too good to be true. This is where the factory should step in. Is anybody from the marauderteam out there?
