I have spare gearbox. It is 5 speed, dual range (1:1.592) gearbox taken of 1800 wagon (carb, non turbo). It has 3 position lever: fwd, 4wd and 4wd reductioned.

The question is: is it 3.7 or 3.9 ratioed ???

http://usmb.ultimatesubaru.org/foru...ear+final+drive says it is 3.9.

I would like it to be 3.9 :-)

But when I check it (turning and counting) it seems to be 3.7 :-(

Being in poland you may have different ratios in your trannies, but look at the old car that you got the transmission out of the rear diff will be the same as the front, in america if its got a 1.59 low range its always a 3.9 and if its an automatic its a 3.7 that seems to be the cutoff, autos are 3.7 and manuals, unless turbo which are 3.7 like the autos, the manuals are all 3.9
