I believe 5th gear because you need to multiply the transfer gear 1.46 (Z51)
Differential 3.55 (ring and pinion)
Z51 DCT:
4th gear .88 X 3.55 (Diff.) X 1.46 {transfer gear} = 4.56
5th gear .65 X 3.55 X 1.46 = 3.36
5th gear because 3.36 is closer to the differential 3.55 than 4.56.
The DCT gears and ring and pinion are the same in both the non Z51 and Z51, except for the transfer gear 1.38 (non Z51) vs 1.46 (Z51).
