Maybe I read the question wrong, but the A/M switch shouldnt make the gears longer or shorter.
The M means it's whatever position your stick is at. If you're in D1(with the M switch engaged), then you get first gear only. D2 (with the M switch engaged), is second only (WITH NO FIRST) and D3(with the M switch engaged), is third only with no first or second. Its just that one gear you get.
I know when you put it in D3 (with the A switch engaged), it latens the shift point and takes 4th away.....
Hope this helps.
