5 Speed swap
Here's an interesting (to me) comparison of some of the available transmissions, excluding the high end ones like a T56 or TKX.
| A833 OD | AX15 | A833 | TKO-500 | A833 HOD |
| 1st | 3.09 | 3.83 | 2.66 | 3.27 | 2.66 |

| 3rd | 1 | 1.44 | 1.39 | 1.34 | 1 |
| 4th | 0.73 | 1 | 1 | 1 | 0.8 |
| 5th | | 0.79 | | 0.68 | |
| | | | | |
| 1-2 drop | 45.95% | 39.16% | 28.20% | 39.45% | 40.23% |
| 2-3 drop | 40.12% | 38.20% | 27.23% | 32.32% | 37.11% |

| 5th | 0 | 775 | 0 | 790 | 0 |
That AX15 with a 2.71 final drive should feel just as good as a Passon Hemi OD box with 3.91's, first through 3rd and would cruise at a much better RPM on the highway.
And it's pretty comparable to a TKO500 with 3.21's outside of 4th.
