A518 (46RH/46RE)[edit]
The A518, later renamed 46RH (hydraulic controlled governor pressure) and 46RE (electronic controlled governor pressure), is an A727 derivative with overdrive, in the A500 ilk. Starting in 1990, it was used in some trucks and vans. The overdrive fourth gear ratio is 0.69:1.

Gear ratios:

1 2 3 4 R
2.45 1.45 1.00 0.69 2.35
Help me out here. So which one would be good to put behind a 450hp 360 magnum with 3.55 gears in the rear?
