Hi can anyone tell me if I swap out my g13bb manual transfer case for a g13bb auto one will it give reduction and if so how much

[jimny_timmy]

From what I have read, they use the same transfer, just different ratios in the diff.

This. ^

It's only VVT where the ratios are different because the VVT manual gearbox has a 1:1 5th so it needed the higher geared transfer case but the auto retained the overdrive top gear so it needed the lower geared transfer.

Ok so g13bb both have same geared transfer

[jimny_timmy]

Yes

[russty_2008]

Ok cheers looks like a wt transfer it is

[monley]

Is it only m series transfers that are different auto to Manual? (27% or something)
