2 different final drive ratios??

[neit_jnf]

Taken from Mazda's MS6 spec sheet, notice the final drives in bold, how can it have 2 different final drive ratios depending on gear?

Transmission ratios 1)

1st 3.538

2nd 2.238

3rd 1.535

4th 1.171

5th 1.085

6th 0.853

Reverse 3.831

Final Drive

1st - 4th 3.941

5th, 6th, Rev. 3.350

​

anyone?



here's a wild guess... it's awd in 1st - 4th gears and this makes the final drive effectivelly shorter for better accel. then in 5th, 6th and reverse it disengages the rear drive and in fully fwd mode the final drive is taller???

but this would mean the final drive continually changes depending on conditions... anybody has an idea?​

1/2/3/4 are on one shaft, 5/6/R on another. Each shaft has different input ratios, accounting for the difference.

It's more common than you might think with 5 or 6 speed transmissions.
