Man that is weird. I can only suspect that being an intended road going 4wd having either the front or rear wheels moving at a slightly different speed may improve the handling of the vehicle.
Well, doing the math for the turbo 3AT I get this,
Front final drive is 3.454545.......
Rear final drive+transfer reduction= 3.4533333.....
So it seems it would actually give the rear and a very
slightly taller gear, so pressumably a bit of rear bias to the power split.
And it seems that this setup was used at least until '86, Just looked in the FSM.
3ATs also have a reduction gear before
either the front diff and transfer gears. Either .974, .933, and 1.026 For turbo/non and 2wd/4wd etc.....too much to list all that.
Now let's get back to the 4sdp. In question. All I can find in my books say the 4spds use 1:1 transfer. SO........
Front diff=3.8888... (35/9)
Rear diff= 3.9 (39/10)
In this case, the rear is slightly lower
ratio.....so a tiny bit of front bias.
Sorry for the hijack. I forgot what this thread was about.
