'11-'17 gearbox ratios (3.31 and 3.73 rear axle)
1 is 3.66
2 is 2.43
3 is 1.69
4 is 1.32
5 is 1.0
6 is .65

MT82 D4 '18 on (US =3.73 rear axle, AUST = 3.55)

1 is 3.24
2 is 2.10
3 is 1.42
4 is 1.0
5 is 0.81
6 is .62

Maybe needs 3.9s or 4.1s for real gains with NA Coyote...

the 3.55s on the '18 on close ratio box would feel like 3.15 rear axle on earlier Mustang
