5.9 Magnum 5-speed In an early A??

Just to flesh it out a little better, while that AX15 has a deep first gear (3.83:1), with a .271 final drive it wouldn't be any worse than a standard 4 speed with 4.10 gears. The 2.66 first gear 4 speed would have an overall ratio of 10.91 while the AX15 would bee 10.38.

And the ratio splits are actually better than an A833OD at 39% 1-2 and 38% 2-3 for AX15 versus 46% 1-2 and 40% 2-3 for the A833OD.

So, while the AX15 might be geared pretty deep and far from ideal, it might still be better than some other options.
