The gear ratios in the semi-auto are the SAME as those used in the manual cars.

Low, D1 and D2 are the SAME gear ratios as 2nd, 3rd and 4th in the manual gearbox. 1st gear is missing in the semi-auto box as the torque converter takes it's place.

The early semi-autos, 68 to 71, used the 1200/1300 diff ratio though - 4.375 instead of the 1500/1600 manual's 4.125. Which means ALL the gear ratios are a fraction lower if you leave the semi-auto gearbox in place, though changing to the 4.125 ratio diff is a straight swap in that box if preferred..
