Ripetide, the automatic's axle ratio is a 3.06 and the manuals is 3.73 for 18 inch rims and 3.92 with 20 inch rims. To put this into perspective the gear ratios for the automatic are as such:

1st 3.59, 2nd 2.19, 3rd 1.41, 4th 1.00, 5th .83

for the TR-6060 it is as such:

1st 2.97, 2nd 2.10, 3rd 1.46, 4th 1.00, 5th .74, 6th .50

This makes the difference in gearing much closer after calculating these together. You will find that the gearing is quite close but ultimately favors the manual.
