How to Drive a Ford Cruise-O-Matic Transmission in Town






The Cruise-O-Matic arrived in 1958 and offered 3 Drive positions, one marked with a green dot. The new automatic still featured a Low position, but a sprag allowed the transmission to shift automatically from low to second to third when in the green dot position. The white dot started in 2 gear and went to 3rd only. This green dot gear pattern remained until 1967, when Ford replaced it with the now-common 1-2-D pattern for three-speeds. 




Frankly, weekend runs down the boulevard using white dot is comfy, responsive (with the 352) and there ain't a day goes by somebody doesn't give me the thumbs up ))
 







From the original 1966 F-250 Camper Special Operators Manual we learn what the crazy dots and L mean when driving the 3 speed Cruise-O-Matic transmission. 

I think the cruise-o-matic (or COM) is a little quirky and a little special - I know nothing of the mechanics but from a drivers view, skipping first gear on a truck geared like this factory standard Spicer/Dana 60 Rear Axle (4.10-1 / No Limited Slip with 5,200 lbs. Rear Axle) made off farm driving a piece of cake. I don't get ice or snow but I find the 2-3 softens the jolts when driving in town and out on the two lane roads in the surrounding low hills. Downside is there is no way to hold the transmission in 2nd gear. On all forward options 2nd gear shifts up.      


I never could resolve the differences in the drive markings of the picture on page 1 and the text. So, I drove it to learn the green dot on my shift indicator shifts 1-2-3, the little white dot under the word Drive started in 2nd and went to 3rd when pushed. L was 1st gear only.   



Best of luck with this ...
