1996 Geo Prizm 1.6 3-Speed Auto Final Drive Ratio

#1
I can't seem to find the final drive ratio for this transmission anywhere online... I calculated it approximately by knowing 2nd gear tops out at 65 and that the redline is 6000 (I don't have a tach). This came up about 4.1 which sounds reasonable, but I don't think the torque converter locks up until 3rd gear so that will throw my approximation off a little.

Anyone know the final drive gear ratio?
