Simple math tells me that pre-facelift FD ratios are 2.74:1 for 1/2/5/6 and 4.05:1 for 3/4/Reverse.

Facelift FD ratios are 2.87:1 for 1/2/5/6 and 4.24:1 for 3/4/Reverse.

Anybody know if that is right?

Jeremy"

Ok so for all years if the input shaft, plus all gears and pinion gears are the same then that chart seems off for 3 gears. I only quickly calculated for just the swap of crownwheel gear from 85 teeth(pre facelift) to 89 teeth(post facelift).

I'm calculating facelift gearbox overall ratios for:

1st gear I come to 11.96:1 not 12.789:1(based on my 12 tooth input to 50 tooth 1st gear).

2nd gear I come to 7.52:1 not 7.793:1.

Reverse I come to 11.65:1 not 11.944:1(based on my 33 tooth reverse and 50 tooth 1st gear).

Bhozar do you have any more top down pics of your facelift gearbox? Then we could easily figure out 1st and Reverse ratios.
