I've been looking for a good T100 for a few months now and I have noticed in looking at a bunch of them that most SR5's with auto tranny's have a A11A axle code which is 4.44 ratio open diff. I drove a '95 T100 DX manual tranny which had an axle code of A10A which is 4.38 but it felt like it had much higher gearing than the axle codes said (more like 3.90). It seemed slow for a manual.

Every T100 I have looked at has had 31's. I want the lowest gears I can get stock and I believe that is A11A in an SR5. Will auto trannies have lower gears than manual tranny SR5's? Some auto's have had great acceleration and others have not while some manuals have had good acceleration and others have not. Why is there such a disparity? All of them have had between 125k and 170k miles.

Do SR5's have lower gears than DX's? Do auto's have lower gears than manuals? Will all manual T100's have A10A axle codes?

Thanks for any help.
